The axle diameter is a 3/8” bolt with a latching nut. You can order an stainless steel lube axle which offers a lubricated fitting in the bolt head to grease the wheel. This stainless steel caster also has a mirror finish available upon request. You can get a large selection of wheels. They are NSF and ROHS compliant. The mounting plate is 2 3/8” x 3 5/8” and the hole pattern is slotted to: 1 3/4” x 2 7/8” – 3” and is designed to use a mounting bolt size of 5/16”. The reason this caster is considered “economy” is lacks the metal shield covering the swivel bearing. K3A Casters also does not come with a lubricated fitting in the swivel bearing. These features are not necessarily negative depending on the application. The shield over the swivel bearing can retain water from a wash down which can produce filthy conditions, depending on the use. This caster is ideal for washdown applications such as an animal lab or butcher table.
