4 Inch Full Black PP Single Ball Bearing M12*30 Swivel Caster - Easy Assembling For Equipment
This caster is designed to provide smooth mobility, precise positioning for equipment, carts, racks, or machinery in industrial, commercial, or workshop environments.
1. Wheel Size: 4 Inch
Feature: The wheel has a diameter of 4 inches (approximately 100mm).
Function: This size provides a balance between floor clearance and load capacity. It rolls over debris and small bumps more easily than smaller 2" or 3" casters, making it suitable for light industrial or commercial use.
Feature: The wheel is made entirely of black Polypropylene.
Function:
Hardness: PP is a rigid, hard material. It offers very low rolling resistance, meaning equipment moves easily on smooth floors.
Chemical Resistance: It is resistant to oils, solvents, and water. It will not absorb moisture.
Floor Protection: While hard, it is generally non-marking (the "full black" helps hide dirt) and is designed for smooth floors like concrete or epoxy, but it can be noisy.
Cost-Effective: PP is an economical material choice.
Feature: The wheel hub contains a single race of ball bearings.
Function: This reduces friction between the wheel axle and the wheel itself. It allows the wheel to spin freely after the initial push, requiring less effort from the user to move and maneuver the load compared to "plain bore" (sleeve bearing) casters.
Feature: The caster mounts via a threaded stem. It has a metric M12 thread (12mm diameter) and a stem length of 30mm.
Function: This is designed to screw directly into a threaded hole or into a threaded insert in the leg of a cart, machine, or piece of furniture. It provides a very secure, vibration-resistant attachment that won't loosen as easily as a standard stem.
Feature: The caster includes a swivel raceway (the part between the top plate and the wheel fork) that allows the wheel to rotate 360 degrees.
Function: This provides steering. Unlike a rigid caster, this swivel function allows the operator to change direction easily. The equipment can be pushed sideways or turned in place.
This specific caster is ideal for:
Light to Medium Duty Equipment: Carts, trolleys, or display racks.
Wet or Chemical Environments: Kitchens, hospitals, or laboratories where the wheel might get wet (since PP won't rust or rot).
Applications requiring secure mounting: Where a standard grip-ring stem might pull out, the threaded M12 stem keeps it locked in place.
