SKF tapered roller bearings handle radial and axial loads at the same time. The tapered design creates linear contact that spreads the load over a wider area, which gives the bearing high capacity and rigidity. You will find them in transmission cases, gearboxes and other industrial equipment where precision and durability matter. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
The part number tells you what you are getting. Take 31308/CL7CDF: the 313 prefix is the dimension series, which sets the bore diameter and the contact angle. CL7C covers the internal clearance, and DF means the item comes as a matched pair of two bearings arranged for tandem mounting. Reading the code this way helps you confirm the bearing matches the application before you order.
These bearings show up in automotive, metallurgical, cement and food processing plants. Typical equipment includes gearboxes, differentials, machine tool spindles, rolling mill rolls and mining machinery. Because they take combined loads and stay rigid, they suit jobs where precision and reliability are critical, even under severe operating conditions.
Selection comes down to load magnitude and direction, rotation speed and the environment. Mounting requires careful alignment and the right lubrication. SKF bearings often arrive prelubricated, but check that the grease is compatible with what is already in the housing. Choose sealing and internal clearance to match the application. Poor installation shortens service life, so follow good mounting practices and use the correct tools.
On interchangeability, SKF tapered roller bearings can be replaced by other brands that share the same dimensions and specifications. Verify internal clearance, tolerance class and assembly design first, since small differences can affect performance. Talk to a specialist before substituting a bearing to confirm compatibility and keep the equipment running as intended.
