3" x 1-1/4" Heavy Duty Plastic Wheel Swivel Caster w/ Total Lock Brake, 1/2"-13 x 1" Threaded Stem - Part # Q523021HDPSWB
Polyolefin is a durable type of plastic that yields a high shock load while offering excellent impact & abrasion resistance. These wheels are lightweight yet hold high weight capacities. Unlike softer tread wheels, these wheels resist flat spotting over time. They are also impervious to water, washable, & highly resistant to chemicals, cleaning solutions, solvents, oils, & grease. These features, combined with their economical price point, make polyolefin wheel casters a popular choice.
We recommend polyolefin for a wide range of applications. However, its hard, non-marking tread can trap dirt & debris, which may scratch delicate floor surfaces, making it a less suitable choice where floor protection is a priority. If this is a concern, we recommend our thermoplastic rubber wheel options, as they offer non-marking floor protection while maintaining the same resistance to environmental factors.
* Total locking brake casters work best with softer wheels like neoprene, soft rubber, thermoplastic rubber & polyurethane. The softer wheel allows the brake pad to grip the tread effectively. While total locking brakes also work with harder wheels, a strong push may cause slight movement of the caster wheel.
* To tighten the caster, locate the 3/4" nut on the underside of the stem & tighten with a 3/4" wrench. Refer to the product images for reference.
NSF Certified: Tested & approved for use in commercial kitchens & food processing environments where cleanliness & contamination control are essential.
