Decoding SKF 31316 J1/QCL7A
- 313Series
- Tapered roller bearings, 313 series. Series differ in outside diameter and width even when the bore is the same.
- 16Bore
- Bore 80 mm (16 × 5).
- J1/QCL7ASuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
31316 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 31316 J1/QCL7A measures 80 mm across the bore and 170 mm across the outside diameter; its total width is 42.5 mm (80 x 170 x 42.5 mm).

SKF tapered roller bearings handle radial and axial forces at the same time. The angled raceways and conical rollers create a line of contact that spreads the load across the bearing. You will find them in gear reducers, transmission housings, wheel hubs, and heavy-duty equipment where stiffness matters. MR Industrial Accessories supplies the SKF range and helps you match the exact designation to your machine.
The part number tells you what you are getting. Take 31316 J1/QCL7A: 31316 sets the boundary dimensions and the contact angle, J1 means a stamped steel window cage held without rivets, and QCL7A points to a special execution with controlled tolerances and internal clearance. Reading those codes correctly lets you order the right replacement the first time and avoid fit-up problems on the shaft.
In US plants and workshops, these bearings show up in speed reducers, gearboxes, rear axles, road-building machines, mining equipment, and mill stands. They also appear in machine-tool spindles and heavy conveyor rollers. Because they take combined loads, they suit shafts that see both bending and thrust. MR Industrial Accessories serves maintenance and purchasing teams across the United States and in several Latin American countries.
Selection comes down to radial load, axial load, speed, and the environment. Sealing is critical: in dusty or wet areas, use sealed variants or make sure lubrication is adequate. Set internal clearance to match the mounting arrangement—too much preload drives up temperature. Shaft alignment and housing seat condition also affect how long the bearing lasts. If any of these points are unclear, ask our technical team before you order.
SKF tapered roller bearings can interchange with other brands when dimensions and the full designation line up. But suffixes are not always equivalent: cage type, tolerances, and clearance can differ from one maker to another. So when you replace, check the complete code, not just the basic number. MR helps you sort out those differences so the substitution works without hurting equipment performance.

Frequently asked questions
- SKF 31316 J1/QCL7A bearing: what are its dimensions?
- SKF 31316 J1/QCL7A measures 80 mm across the bore and 170 mm across the outside diameter; its total width is 42.5 mm (80 x 170 x 42.5 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 31316.
- What does the J1 suffix mean on an SKF bearing?
- J1 indicates a stamped steel window cage without rivets. That cage keeps the rollers aligned and handles moderate loads. Always include the suffix when you order a replacement to ensure it fits and works as intended.
- Do I need the QCL7A suffix?
- QCL7A denotes a special execution with controlled tolerances and clearance. If your original equipment calls for it, keep it to avoid changing how the bearing runs. Send us the full part number and we can confirm what you need.
- Can I use another brand instead of SKF?
- Yes, as long as the dimensions and the complete designation, including suffixes, match. Cages, tolerances, and clearances can vary between manufacturers, so verify that the alternative meets your original specifications.
