You're viewing caster wheel SKU W-8-PR-3/4 on CasterConnection.com.
Like an automobile tire, the low speed industrial Pneumatic Wheel uses air pressure to provide shock absorption, quiet operation, and ease of rolling over rough terrain.
The 8", 10, & 12" models were recently upgraded to a stronger one-piece black rim. The one-piece rim is more durable than the demountable rim it replaces, and you no longer have to worry about bolts in the rim coming loose or falling out - an important factor in aircraft engine environments.
The wheels are also newly available with maintenance-free sealed precision ball bearings.
. This wheel includes a Tapered Roller Bearing with a caster hub length of 4-7/8".
