Deep Groove Ball Bearings SKF 6336 M/C3

Single-row SKF deep groove ball bearing 6336 M/C3 with a 180 mm bore, robust brass cage and increased C3 bearing clearance for demanding applications in heavy industrial machinery.

The 6336 M/C3 deep groove ball bearing is a single-row heavy-duty rolling bearing made from standard 100Cr6 bearing steel. With key dimensions of 180 mm inner diameter, 380 mm outer diameter and a width of 75 mm, this roller bearing can accommodate significant radial loads as well as axial forces in both directions. Manufactured to the standard tolerance class P0/PN (ABEC 1), the outer ring has a cylindrical shape without a groove or flange. The open design allows for flexible lubrication via the respective unit.

What is the 6336 M/C3 deep groove ball bearing suitable for?

Designs with large shaft diameters require bearings capable of withstanding high mechanical loads. The 6336 M/C3 deep groove ball bearing is used for the reliable support of heavy shafts in general mechanical engineering, in industrial gearboxes and in heavy-duty conveyor and drive systems. As the bearing has an open design, it can be integrated directly into external oil or grease lubrication systems. The permissible temperature range of –20 to +150 degrees enables stable operation even when the surrounding components heat up significantly during operation.

What is the function of the brass cage and the C3 clearance in this bearing?

The suffixes provide information on specific design features: the ‘M’ denotes a solid brass cage, which guides the balls precisely and is resistant to vibrations and high acceleration forces. The ‘C3’ designation stands for a slightly increased radial clearance. This compensates for thermal expansion or contraction during operation caused by tight fits, preventing stress build-up. For the open design, designers should provide an effective housing seal to retain the lubricant and keep out particles.
