Engineered for Durability
Through-Hardened Bearing Steel
High-grade chromium steel (100Cr6) with uniform hardness throughout, providing outstanding fatigue resistance under continuous heavy radial loads.
Optimized Roller Profile
SKF's E-design features a modified internal geometry with optimized roller and raceway profiles, significantly reducing edge stress concentrations and extending service life.
Precision-Ground Raceways
Superfinished raceway surfaces with tight dimensional tolerances ensure smooth rotation, reduced vibration, and consistent performance across the full speed range.
ISO 9001 & TS 16949 Quality Control
Every bearing undergoes multi-stage dimensional verification, noise testing, and pre-shipment inspection under certified quality management protocols.
NU312 Series & Alternatives
Explore compatible variants and adjacent series for your specific load and mounting requirements.
Polyamide cage for higher speed capability and reduced friction. Ideal for high-speed spindle applications.
Machined brass cage for extreme temperature environments and heavy vibration conditions in industrial machinery.
One-side inner ring flange enabling axial location in one direction. Suitable for combined radial and axial load arrangements.
Flanged inner ring on both sides for axial location in both directions. Widely used in gearboxes and pump applications.
Adjacent series with 55mm bore. Interchangeable design for compact shaft arrangements requiring reduced dimensions.
Step-up model with 65mm bore and higher load capacity. Preferred for heavier shaft loads in industrial gearboxes.
Wide series variant (52mm width) with significantly higher radial load capacity for extreme-duty applications.

Built for Demanding Industries
The NU312E is widely deployed across sectors where radial load capacity, precision, and long service life are non-negotiable.
Why Choose SKF NU312E?
Engineered with SKF's proprietary E-design technology, the NU312E delivers measurably superior performance compared to standard cylindrical roller bearings.
Extended Service Life
The E-design's optimized roller and raceway geometry distributes contact stress more evenly, substantially extending calculated bearing life under equivalent load conditions.
High Radial Load Capacity
With a dynamic load rating of 148 kN, the NU312E handles substantial radial forces in compact shaft arrangements without compromising rotational accuracy.
Broad Speed Range
Reference speed of 5,300 rpm and limiting speed of 7,000 rpm make the NU312E equally effective in low-speed, high-load and medium-speed precision applications.
Verified Authenticity

Common Questions
Quick answers to the most common questions about SKF NU312E ordering, delivery, and specifications.
What is the difference between NU312E and NU312ECP?
The NU312E uses a pressed steel cage, while the NU312ECP uses a glass-fibre reinforced polyamide (PA66) cage. The ECP variant offers higher speed capability and lower friction due to the lighter cage material. For standard industrial applications with moderate speeds, the NU312E is typically sufficient. For higher-speed spindle or precision applications, NU312ECP may be preferable.
Ask on WhatsAppHow do I verify that the bearings are genuine SKF products?
All bearings we supply come with complete traceability documentation including manufacturer certificates, batch numbers, and inspection records. SKF bearings also feature laser-marked markings and packaging with security features. We provide full documentation packages suitable for supplier audits and incoming quality inspection processes.
Ask on WhatsAppWhat is the minimum order quantity (MOQ) for SKF NU312E?
There is no strict minimum order quantity for standard stock items. Single pieces can be ordered for maintenance and replacement purposes. For volume pricing and priority fulfillment, we recommend orders of 10+ pieces. For orders exceeding $50,000 USD in value, complimentary sample units are available for pre-production testing and approval.
Ask on WhatsAppWhat are the typical delivery lead times for international orders?
For in-stock items, orders are typically dispatched within 1-3 business days. Air freight delivery to major international hubs takes 3-7 business days. Sea freight for larger volume orders takes 15-30 days depending on destination. Expedited options are available for urgent requirements. Specific timelines for your location can be confirmed on WhatsApp before order placement.
Check Delivery TimeCan NU312E handle both radial and axial loads simultaneously?
The NU312E (NU-type) is designed primarily for radial loads. The NU design has no inner ring flanges, meaning the inner ring can move freely in the axial direction -- it does not accommodate axial loads. For applications requiring axial location in one direction, the NJ312E is recommended. For axial location in both directions, consider the NUP312E. Contact us to confirm the optimal bearing type for your specific load arrangement.
Ask on WhatsAppDo you supply other SKF bearing types beyond the NU series?
Yes. We maintain comprehensive stock across all major SKF bearing families including deep groove ball bearings, angular contact ball bearings, spherical roller bearings, taper roller bearings, thrust bearings, and linear bearings. Beyond SKF, we carry 500+ brands including FAG, NSK, NTN, TIMKEN, KOYO, INA, and more. Share your full bearing list on WhatsApp for a consolidated quote.
