Wheel Brakes are not designed to hold on inclines:
Swivel Construction Stamped steel. Swivel has double ball bearing with hardened raceways. Metal cover shields swivel bearings from dirt and dust.
Finish: external metal parts are Zinc plated.
Axle is 3/8″ diameter bolt with lock nut.
Axle – 1/2” diameter hollow bolt with lock nut.
Center Pin is a 1/2″ diameter steel rivet.
Wheel Bearing Types (PS= Precision Sealed Ball Bearings, B= Ball Bearings, D= Delrin Bearings, RB= Roller Bearing, P= Plain Bore.)
Deduct 1/4 lb. for weight of rigid caster.
Use the Polyolefin ( Industrial Plastic ) wheel for “Standing Loads”. Polyolefin wheels eliminate the possiblilty of a flat spot developing if the castered equipment is left parked for a prolong period.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
