SL series caster
A new low profile caster features a maintenance-free precision ball bearing wheel that provides low friction when moving equipment over level surfaces. The bearing is shielded to prevent dirt and grit from entering, while retaining the lubricating grease for long, smooth operating, life, the company states. The new SL series caster has a 2" diameter polyurethane wheel and overall height of only 2-1/2", making it ideal for business machines and other specialized applications, according to Revvo Catser. It has a load capacity of 350lbs, tread width of 1-1/16" and swivel radius of 2". The top plate has mounting holes to suit 1/4-inch diameter countersink head screws.
