Lab & Scientific Products By CasterHQ

• Heavy Duty Construction & Load Capacity: Designed with 1/4\" thick cold-rolled steel yokes, double ball raceways, and a 5/8\" kingpin, these swivel casters handle up to 5,000 lbs per set of 4 (1,250 lbs per caster). The non-marking red polyurethane tread on a heavy-duty steel core ensures durability, floor protection, and smooth mobility, making it ideal for heavy equipment, toolboxes, and workbenches.
• Technical Specifications & Mounting Details: Each caster has an overall height of 7.5\", with a 4\" x 4-1/2\" plate size and a slotted bolt hole pattern of 2-5/8\" x 3-5/8\" (to 3\" x 3\") for versatile mounting. Equipped with 3/4\" roller bearings and a 1/2\" spanner with a zerk axle and lock nut, these casters provide added safety, stability, and easy maintenance through grease fittings in the raceway and axle.
• NSF Listed & Certified for Reliability: Built for industrial performance, these casters are NSF Listed, RoHS Compliant, and ANSI Tested for safety and reliability. Heat-treated ball bearings and a bright zinc-plated finish offer excellent rust resistance, while optional matching total-locking casters are available for added functionality and security.
