Description

SEMI-PNEUMATIC WHEELS – PUNCTURE PROOF TYRES:

Polyurethane foam-filled tyres are the premium ‘pneumatic’ (or semi-pneumatic) wheel option: the wheels are puncture proof and provide the greatest performance and reliability. Semi-pneumatics are fitted to two piece wobble-free steel centres. Manufactured from 1.8mm steel.

[NOTE: some of the cheaper centres on the market are manufactured from steel as thin as 0.6mm]

BEARINGS:

‘Deep Groove’ shielded bearings fitted to a toughened heavy duty housing enables true running and extra strength (NOTE: Deep groove bearings can last up to 3 times longer than normal pressed bearings).

TYRES:

4 ply for longer, rougher life (many imports use 2 ply).

For wheels pulled or pushed at low speeds (not driven) the tread pattern is not critical. The following are standard; other patterns can be offered by negotiation.

• RIB: Straight lines along the tread, common on wheelchairs.
• LUG: General purpose, outside use. Strongly marked cross lines on a fairly flat tread surface. Good for running in a straight line.
• LGG: Grey rubber LUG – non-marking of floors
• DMD: Diamond shaped pads on a flatter surface. Often used in rougher construction sites. Good for softer grassed surfaces, but may become clogged with mud.
• ZGG: Grey rubber zig zag – non-marking of floors
• KNO: This knobbly pattern is often preferred for outdoor use, where its strongly marked tread takes a good grip on soft ground.
