Light Duty Casters

Light duty casters cover the most common industrial loading: small trolleys, workbenches, parts carts, office and contract furniture, and light fixtures, with 1 to 5 inch wheel sizes and ratings from 10kg to 100kg per wheel. The line is built on the Sumatic 01 and 011 series forks in swivel and rigid, with top plate or threaded stem mounting.

Light duty does not mean low reliability: the load calculation is the same as for heavy equipment. Divide the maximum loaded weight by the number of casters and apply a 2.5 safety factor for swivel casters on hard floors. A 100kg loaded parts trolley on four casters needs a 63kg rating, which points to 3-4 inch casters in this line. A 40kg workbench runs on 2.5-3 inch units at 25-35kg ratings.

Wheel material follows the floor. PVC is the quiet default for painted, resin and epoxy floors and for indoor office use. TPR gives a softer roll with lower push-back force for furniture and light trolleys. PU adds abrasion resistance for high-cycle routes and forklift traffic zones. Where the floor is unknown, PVC is the safe first order and the wheel can be swapped later because the fork stays the same.

Mounting is split evenly between the two options in this class: top plate casters with 2 or 4 holes dominate on fabricated trolleys and benches, while threaded stem casters (M8-M12) are common on cast bases, tool chests and older equipment where tapping holes is standard. Swivel plus rigid pairing is the norm, with two swivel and two rigid per unit.

Sumatic produces forks, bearings and wheels in-house, so light duty programmes can standardise one fork family across every size and compound on this page. Finishes cover zinc, nickel and black epoxy, and wheel colours include black, grey and off-white for asset identification or furniture matching.
