Engineered for
Extreme Demands
Every SKF 1312 bearing undergoes rigorous material selection and precision manufacturing to deliver consistent performance across the most challenging industrial conditions.
High-Grade Bearing Steel
Manufactured from high-carbon chromium bearing steel (GCr15 / 52100) with optimized heat treatment for maximum hardness and fatigue resistance.
Precision-Ground Raceway
CNC-precision ground inner and outer raceways ensure consistent ball contact geometry, reducing vibration and extending service intervals.
Polyamide / Steel Cage Options
TN9 polyamide cage for high-speed, low-noise applications; steel cage variants available for elevated-temperature and heavy-load conditions.
ISO Dimensional Accuracy
Manufactured to ISO 492 tolerances (Normal class). EKTN9 suffix indicates a tapered bore (1:12 taper) for adapter sleeve mounting.
Trusted Across Industries
The SKF 1312 bearing series is deployed across a wide range of demanding industrial sectors worldwide.
Performance Advantages
Designed to solve the real-world challenges that cause bearing failures -- misalignment, vibration, and premature wear.
Self-Aligning Design
The spherical outer raceway allows up to 2.5° of angular misalignment, compensating for shaft deflection and housing inaccuracies that would otherwise cause premature failure.
Extended Service Life
Optimised internal geometry and precision-ground raceways deliver superior fatigue resistance, significantly reducing unplanned downtime and total maintenance costs.
High-Speed Capability
Reference speed of 6,300 rpm with the TN9 polyamide cage enabling quiet, low-friction operation in high-speed textile and packaging machinery.

What Our Clients Say
Procurement directors and plant managers share their experience working with SKF China.
"We've been sourcing SKF 1312 bearings for our conveyor lines for two years. Consistent quality, fast delivery, and the documentation package satisfies our European compliance team every time."
"Our textile plant upgraded all spindle bearings to SKF 1312 series. The reduction in vibration was immediate and measurable. Highly recommend for high-speed applications."
"Ordered 500 units of SKF 1312 for our paper mill upgrade. Arrived within 10 days with full QC certificates. The self-aligning feature solved our chronic misalignment issue completely."
"Price-competitive with faster lead times than our previous supplier. The ISO documentation is thorough and accepted by our quality auditors without question."
"We replaced competitor bearings with SKF 1312 in our fan assemblies. The difference in operating temperature and noise level was significant. Very satisfied with the product quality."
"Fast response, competitive price, and the bearings performed exactly as specified. We've now standardised on SKF China as our preferred supplier for the entire 1300 series."
