Product type: 6300 series high-load deep groove ball bearings
Bearing structure: Deep groove ball bearing with larger outside diameter and wider rings than comparable 6000 or 6200 series sizes. Open, ZZ metal-shielded and 2RS rubber-sealed versions are available. Material options include high carbon steel, bearing steel, stainless steel and customized specifications.
The 6300 series is intended for industrial machinery, transmission equipment and heavy-duty roller systems where sufficient installation space is available. Compared with the 6000 and 6200 series of the same bore size, the 6300 series normally has a larger outside diameter and wider rings, allowing it to carry higher radial loads.
The deep raceway supports radial loads and limited axial loads in both directions. Common models listed in the page description include 6300, 6301, 6302, 6303, 6304 and 6305. Open, ZZ and 2RS versions can be selected for different speed, dust and moisture conditions, and the bearing can be assembled with plastic, rubber, steel or other metal outer wheels.
Product Applications
A 6300 series deep groove ball bearing is suitable for equipment that needs higher radial load support and has enough space for the larger bearing section. Typical applications include:
Heavy-duty industrial rollers: the larger bearing structure supports roller wheels used in demanding industrial equipment.
Sliding gate and large door rollers: the bearing can be integrated into heavy roller assemblies for gate and large-door systems.
Conveyor systems: the bearing supports rotating rollers, pulleys and guide components in material-handling equipment.
Electric motors and generators: the deep groove structure supports shaft rotation and limited axial positioning loads.
Pumps and industrial fans: the bearing can be selected for rotating assemblies where radial load and installation space have been confirmed.
Gearboxes and transmission equipment: the bearing supports rotating shafts in compact and medium-size drive systems.
Agricultural machinery and material handling: the bearing can be used in rollers and rotating components exposed to regular industrial duty.
Custom bearing pulleys and guide wheels: the bearing can be matched with a plastic, rubber, steel or metal outer wheel.
