Not all wheels are made the same! June 05, 2019 - Posted in: News

In the following post we will list what the main wheel materials are and the advantages of using them. There are four main core material categories being; Rubber, Polyurethane, Synthetics and Metal. All of these categories have sub-materials and are very important to consider when selecting your next batch of wheels and castors.

Rubber

Tread material: Solid rubber

Solid rubber tyres are universally suitable, vibration-absorbing, shock-resistant, very floor-preserving and resistant to many aggressive substances, except oils (refer to ‘Chemical resistance’, page 36-37). Colour black, grey or dark grey. Solid rubber tyres are suitable at temperatures between -30° C and +80° C. The hardness is 80°+5°/-10° shore A. For high temperature applications up to +260° C special heat-resistant tyres are used.

Extra Options:  Non-marking, grey, electrically conductive, leak resistance <104 Ω

 

Tread material: Thermoplastic rubber-elastomer (TPE)

Thermoplastic rubber-elastomers are floor-preserving, non-marking and offer a high operational comfort, low-noise operation, low rolling and swivel resistance and are resistant to many aggressive substances (refer to ‘Chemical resistance’, page 36-37). Colour grey. Thermoplastic rubber-elastomers are suitable at temperatures between -20° C and +60° C. The hardness is 85°±3° shore A. This material contains traces of oil. On absorbent surfaces this can cause some staining.

Extra Options:  Electrically conductive, non-marking, grey, leak resistance <104 Ω

 

Tread material: Soft rubber

‘Blickle Soft’ soft rubber tyres are characterized by a specially developed, highly elastic, soft rubber compound. These tyres are exceptionally floor-preserving, vibration-absorbing and resistant to many aggressive substances except oils (refer to ‘Chemical resistance’, page 36-37). They also offer highest operational comfort, low rolling resistance on uneven surfaces and are suitable as puncture-proof replacements of pneumatic tyres. Colour black. ‘Blickle Soft’ soft rubber tyres are suitable at temperatures between -30° C and +80° C. The hardness is 50°+5° shore A.

Extra Options:  Non-marking, grey

 

Tread material: Two-component solid rubber

‘Blickle Comfort’ two-component solid rubber tyres are very floor-preserving, vibration-absorbing and resistant to many aggressive substances except oils (refer to ‘Chemical resistance’, page 36-37). Colour black. ‘Blickle Comfort’ two-component solid rubber tyres are suitable at temperatures between -30° C and +80° C. Due to the special structure with hard rubber core (90° shore A hardness) and highly elastic rubber tread (65°±4° shore A), they have a higher load capacity and a lower starting and rolling resistance than solid rubber and offer a very high operational comfort.

Extra Options:  Non-marking, grey (hardness: 56°±4° shore A)

 

Tread material: Elastic solid rubber

Elastic solid rubber tyres are characterized by a special rubber compound. These tyres are very floor-preserving, vibration-absorbing, offer a particularly high load capacity, very high operational comfort and are resistant to many aggressive substances except oils (refer to ‘Chemical resistance’, page 36-37). Colour black. Elastic solid rubber tyres are suitable at temperatures between -30° C and +80° C, temporarily up to +100° C and are available in two versions: n Smooth rolling quality: This version is characterized by a particularly low starting and rolling resistance with high abrasion resistance. The hardness is 65°±3° shore A. n Drive-quality: This version has a very high abrasion resistance with low starting and rolling resistance. The hardness is 65°±3° shore A.

Extra Options:  Non-marking, grey, non-marking, blue, non-marking, natural colour, friction wheel quality, 70°±5° shore A , electrically conductive, leak resistance <104 Ω

 

Tread material: Pneumatic tyres

Pneumatic tyres are made of rubber, are exceptionally floor-preserving, vibration-absorbing and resistant to many aggressive substances except oils (refer to ‘Chemical resistance’, page 36-37). These tyres also offer highest operational comfort and a low rolling resistance on uneven surfaces. The tyre thickness (strength of the carcass) is indicated by the ply rating number. The higher the ply rating number, the better the strength. Light tyres have a ply rating of 2 to 4, heavy tyres 6 to 10. The strength of the carcass determines the maximum tyre pressure and the load capacity. In order to ensure an optimum efficiency and a long service life, the tyre pressure values specified in the respective tables must be therefore strictly adhered to and regularly checked. A tyre pressure which is either too high or low can damage or destroy the tyre. Colour black. Pneumatic tyres are suitable at temperatures between -30° C and +50° C. Wheel or tyre dimensions are valid for unloaded, new tyres and may slightly change in width and diameter during operation.

Extra Options:  Non-marking, grey

 

Tread material: Super-elastic solid rubber

Super-elastic solid rubber tyres are multi-component tyres. The rubber core consists of a hard and tough rubber compound with reinforced steel-wire which ensures a firm tyre seat on the rim even with high loads. A highly elastic cushion layer ensures a low tyre temperature even with high loads and at high speeds. The thick, abrasion-resistant tread protects the tyre against external damages and guarantees a long service life. Based on the special structure, the tyre is particularly suitable for extremely rough conditions. These tyres are very floor-preserving, vibration-absorbing and resistant to many aggressive substances except oils (refer to ‘Chemical resistance’, page 36-37). Colour black. Super-elastic solid rubber tyres are suitable at temperatures between -30° C and +80° C, temporarily up to +100° C. They also offer high operational comfort and a low rolling resistance on uneven surfaces. The advantages over pneumatic tyres are as follows: Puncture-proof and maintenance-free, good stability, structural stability, precise steering behaviour and an abrasion-resistant tread. Wheel or tyre dimensions are valid for unloaded, new tyres and may slightly change in width and diameter during operation.

Extra Options:  Non-marking, antistatic, leak resistance ≤107 Ω

 

Tread material: Silicone rubber

Heat-resistant silicone-elastomer is very floor-preserving, non-marking, abrasion-resistant, highly elastic, suitable for autoclaves, does not degrade over time, odourless, tasteless, physiologically harmless and resistant to many aggressive substances and UV radiation. The material is, however, not resistant to strong lyes, chlorinated and aromatic hydrocarbons. Silicone-elastomers only have moderate mechanical characteristics. They offer a very high operational comfort and only insignificant permanent deformation. Colour black. Heat-resistant silicone-elastomer is suitable at temperatures between -30° C and +250° C. The hardness is 75°±4° shore A.

Extra Options: Non-marking, grey

Phenolic wheels are only conditionally suitable for uneven floors and crossing thresholds due to the high abrasion and the limited mechanical stability of phenolic resin. Colour black. Phenolic resin is suitable at temperatures between -35° C and +260° C, temporarily up to +300° C. The hardness is 90°±3° shore D.


Metals

Cast iron is suitable at temperatures between -100° C and +600° C. The graphite embedded in the cast iron ensures some rotation for plain bores even without grease and reduces the sensitivity to corrosion. The hardness is 180 – 220 HB. The relatively high floor pressure should be considered for pressure-sensitive floors.

 

Tread material: Steel

Mild steel, that is particularly suitable for wheels, extreme pressure and wear-resistant, extremely high static and dynamic load capacity. Tensile strength and hardness remain almost constant over a wide temperature range, oil-resistant. Steel is suitable at a temperature between -100° C and +600° C. The hardness is 190 – 230 HB. The relatively high floor pressure should be considered for pressure-sensitive floors.
