Call Phil for any questions regarding the best wheel for your application.
Straight Roller Bearings: Standard bearing for general duty applications, cost effective, best bearing for abusive and shock load applications. Not recommended for applications where side thrust is possible or on casters used in constant circular turns. Easy to lube but requires periodical lubrication.
Caged Roller Bearings: Take more abuse than standard roller bearings because they are encased with a metal outer race to protect the rollers.
Sealed Precision Ball Bearings: Sealed precision bearings offer low rolling resistance and require the least amount of force to start and maintain a rolling load; excellent for both manual mobility and tow line applications. Maintenance free!! Two top hat spanner bushings are added to secure precise spacing and stability. Not recommended for side thrust or shock load applications. No lube necessary for sealed bearings.
Delrin Bearings: Delrin bearings are a great option for applications with washdown or chemicals are present to the wheels. The delrin bearing will not rust or corrode under harsh environments and have no moving parts to break. They are strong and economical and do not require lubrication.
Four Position Swivel Lock can be used to bolt onto the medium duty swivel lock top plate. The spring loaded plunger is engaged by pulling the key ring and turning to lock and unlock the plunger into the knotches in the swivel raceway locking the swivel action every 90 degrees.
