50mm Nylon Swivel Caster - PTW50507BK

About This Caster - PTW50507BK

Pick this 50mm Source II swivel when a small leg has a 5/16-18 threaded socket and the cart carries a light load.

The 1-inch threaded stem screws into a 5/16-18 insert and snugs with a nut, a positive mount that holds where a press-in stem could work loose on a bumped leg. The Source II is an all-nylon build, body and wheel both, which keeps it economical, and the white nylon wheel resists moisture and chemicals and holds to 250°F. The plain bearing keeps the roll simple, and at 50mm it keeps a light chair base or instrument stand close to the floor.

Ideal applications

• Small legs with a 5/16-18 threaded socket, light load
• Bumped legs where a threaded stem holds better than press-in
• Economical nylon wheels near heat or chemicals to 250°F

For a corner that must park and stay put, the tread-lock PTW50507BK-B adds a wheel lock.

Pairs with: matching threaded-stem Source II swivels on the other legs of the same base.
