Back Designs - Braking Chair Caster, 50 mm, hard

Friction ring stem is compatible with most - but not all - chairs and stools.

11 mm (1/3") diameter;
19mm (3/4") long.

(a.k.a., Safety caster; Self-braking caster; Automatic-braking caster; Unoccupied-braking caster; Unloaded-braking caster)

A safety caster allows free chair movement when you are sitting, but resists unwanted chair movement when you rise. It prevents unwanted or unexpected movement of the chair away from the user. In some European countries all chairs must have safety casters. In the USA, theses casters are primarily used by injured or disabled workers and on sloping floors.

Important! Safety casters may not release and roll if you weigh less than 120 pounds.

Price is for one (1) caster. Order a quantity of five (5) casters for a typical 5-star chair base.

  Specifications

• Caster body is made of high impact modified polyamide 6.
• 50 mm (1.96") wheel-diameter.
• Sturdy 135 lb. load capacity per caster.
• Hard non-marking and non-abrasive tread is designed for carpeted floors.

  Installation instructions

Sticky casters can usually be remedied with a thorough cleaning to remove accumulations of hair and debris in the caster wheels. If after cleaning the casters still do not turn easily, they should be replaced.

1. Turn the chair on its side.
2. If you have strong hands, you can remove the castors by pulling. Otherwise you may need a lever, for example, a chisel or a screwdriver which you place between the castor and the chair base. If the castor stem remains caught in the base, grip the stem with pliers and pull it out. You may need to tap the pliers with a hammer until the stem loosens.
3. Push the new castor into place.
