Steel

Flanged wheels can be used for guidance paired with an unflanged rail wheel to allow a wide tolerance in the pitch of the rails.
MATERIAL: Steel to BS970; Part I: 1983: 080M40
OPERATING TEMPERATURE RANGE:
Plain bored or keywayed wheels -30ºC to 350ºC
Ball or taper roller bearinged wheels -30ºC to 120ºC
The ´maximum load rating´ given for each wheel is based on the full tread width being in contact with the rail. Working loads must be calculated based on the useable rail width and operating conditions - see ´Design Data´ paras. 5.1 and 5.3.
Alternative bore/bearing diameters and alternative bearing types (i.e. bronze bushes, self-lubricating bushes, roller bearings, spherical roller bearings, etc.) are available to order - see ´Design Data´ para. 6.0.
Plain bore wheels are not drilled and taped for greasing unless requested at time of order.
