Engineered for heavy-duty performance, the 6314N deep groove ball bearing with brake groove on the outer ring sets a new benchmark for reliability in commercial vehicle drivetrains. As a core component of Howo/Sitrak truck parts, this bearing is meticulously crafted to withstand extreme loads, high temperatures, and continuous operation. The integrated brake groove enables seamless interaction with braking systems, reducing noise and vibration while extending service life. Whether you are maintaining a fleet or overhauling a single axle, the 6314N ensures your truck stays on the road with minimal downtime.
The 6314N features a specially machined brake groove on the outer ring, allowing for precise alignment with brake calipers and sensors. This design reduces friction peaks and prevents premature wear, a common issue in standard bearings.
Manufactured from high-carbon chromium steel, the bearing offers exceptional hardness (HRC 60-64) and fatigue resistance. The raceway is super-finished to Ra ≤ 0.1 µm, ensuring silent operation even under heavy braking.
Each unit is 100% tested for dimensional accuracy, radial clearance, and brake-groove depth. The 6314N complies with ISO 15 and DIN 625 standards, making it a direct replacement for OEM specifications.
Operating temperature range: -40°C to +160°C. The bearing is pre-lubricated with high-temperature lithium grease, reducing maintenance intervals and improving overall axle efficiency.
Proper installation of the 6314N requires a clean housing and accurate press-fit. Use an induction heater to warm the bearing to 100–110°C for easy mounting. Never hammer the outer ring.
Re-grease every 50,000 km or during brake inspection. The brake groove should be free of debris; a soft brush and non-corrosive cleaner are recommended.
Regular vibration analysis can detect early wear. The 6314N’s groove also acts as a visual wear indicator – when the groove depth reduces by 0.3 mm, replacement is advised.
Pair with premium seals (e.g., SKF or Corteco) to maximise contaminant exclusion. The bearing is compatible with most Howo/Sitrak axle housings from 2010 onwards.
The deep groove ball bearing is more than a replacement part – it is a strategic upgrade for any Howo or Sitrak truck. The brake groove on the outer ring provides a unique advantage, enabling integrated braking feedback and reduced component stack-up. Fleet operators report fewer unscheduled stops and lower total cost of ownership after switching to this bearing.
Backed by rigorous quality assurance and a 24-month warranty (against manufacturing defects), the Deep Groove Ball Bearing ensures peace of mind. Its precision-ground raceways and optimized cage design minimise heat generation, even during mountain descents or urban stop-and-go traffic. Choose the bearing that keeps your cargo moving and your drivers safe.
With thousands of units in service across Europe, Asia, and the Americas, the Deep Groove Ball Bearing has proven its durability in the most demanding conditions. Whether it is a long-haul tractor or a heavy-duty dump truck, this bearing delivers consistent performance. The brake groove not only aids in braking efficiency but also simplifies maintenance checks – a true engineering refinement for modern commercial vehicles.
Always refer to the vehicle’s service manual for specific torque and clearance values. The 6314N is designed for professional installation.
