RWM’s Pneumatic Casters are designed for applications that require a cushioned ride, including but not limited to carts and trucks carrying sensitive materials and parts, glass, ceramics, electronics, chemicals, sound and lighting equipment, movie production equipment (ie: cameras), etc. Pneumatic casters are also useful on uneven floors and outdoor environments.
46 SERIES
Swivel Section: Cold formed top plate, yoke and button are all heat treated to prevent brinelling, improve swivel action and increase service life. Load and thrust bearings are hardened and ground and rotate on hardened raceways. All swivel sections are equipped with a lubrication fitting for field maintenance. Notched yokes are standard. Zinc plated finish to protect from corrosion.
65 SERIES
Raceway Design: Patented Kingpinless™ single ball bearing precision machined raceway, to 53 Rockwell C minimum, lube fittings for swivel bearings and for wheel bearings. Swivel section features a 2-3/8″ diameter raceway with 3/8″ ball bearings. Notched yokes are standard. Zinc plated finish to protect from corrosion.
76 SERIES
Raceway Design: Patented Kingpinless™ single ball bearing precision machined raceway hardened to 53 Rockwell C minimum. Swivel section features a 3″ diameter raceway with 1/2″ ball bearings. Lube fittings for swivel bearings and wheel bearings. Notched yokes are standard. Laguna blue powder coat finish.
95 SERIES
Raceway Design: 4-1/2″ diameter raceway with 3/4″ diameter carbon steel balls. Precision machined and hardened to 53 Rockwell C minimum. Load and thrust are accommodated by our patented Kingpinless™ design. Sealed raceway is standard. Swivel Top Plate – SAE 1045 hot steel forging. Swivel Yoke Base – SAE 1045 hot steel forging. Laguna blue powder coat finish.

To order a rigid caster, change the “S” to “R” in the model number. For example: “76-FNR-1857-R”. To order rig only, omit the blue letters. For example: “76–1857-S”. Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid casters, deduct 9.6 pounds per item.
* Height may vary
*** 6 ply
**** 10 ply
4 ply is standard. Maintain proper air pressure for best results.
Capacity rating is for manual operation. For capacities of power
moved loads, larger diameter or higher capacity heavy duty wheels,
please consult the factory.
