Decoding SKF 31314/CL7A
- 313Series
- Tapered roller bearings, 313 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- CL7ASuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
31314 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 31314/CL7A measures 70 mm across the bore and 150 mm across the outside diameter; its total width is 38 mm (70 x 150 x 38 mm).

SKF tapered roller bearings handle radial and axial loads at the same time. The cone geometry creates linear contact that spreads force across the raceway, which suits tough operating conditions. MR Industrial Accessories supplies this line to customers throughout the United States and in several Latin American countries. If you are unsure which bearing fits your application, our team can help you read the designation and pick the right configuration.
The part number carries the key selection data. Take 31314/CL7A: 31314 sets the size and geometry under international standards, while CL7A points to a specific cage and mounting specification. Reading these codes correctly matters for interchangeability and for getting the performance you expect. When in doubt, send the complete part number and we will help you identify it.
You will find these bearings in gearboxes, conveyor belts, mills, presses and earthmoving equipment, across industries such as metallurgy, cement, mining and food processing. Because they take combined loads, they fit applications where the force direction changes, including industrial vehicle wheels and machine tool spindles.
Selection depends on load magnitude and direction, rotation speed and the surrounding environment. Mounting calls for precise alignment and proper lubrication; in dirty or wet areas, add seals or other protection. Internal clearance also affects running behavior, since a poor fit can lead to overheating or early wear. Follow the manufacturer's guidance for mounting and lubrication.
Tapered roller bearings are made to international standards, so cross-referencing between brands is common. Suffixes and tolerances can still differ, so check the critical dimensions and specifications before swapping one bearing for another make. Our team can review the options with you.

Frequently asked questions
- SKF 31314/CL7A bearing: what are its dimensions?
- SKF 31314/CL7A measures 70 mm across the bore and 150 mm across the outside diameter; its total width is 38 mm (70 x 150 x 38 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 31314.
- What does the CL7A suffix mean in the designation?
- CL7A is a manufacturer-defined cage and mounting specification. It is not a universal code, so confirming its exact meaning requires the technical documentation. Send us the complete part number and we will help you identify it.
- How do I choose between a tapered roller bearing and a ball bearing?
- Tapered rollers support higher combined radial and axial loads than ball bearings, but they allow less speed. For heavy loads at moderate speeds, tapered bearings are usually the better fit. For light loads at high speeds, consider ball bearings.
- What lubrication do you recommend for these bearings?
- It depends on speed, temperature and environment. High-viscosity grease is generally used for slow applications and oil for high speeds. Follow the manufacturer's instructions and keep the bearing clean. We can advise based on your equipment and working conditions.
