UH Series Insert Bearings Product Features
Unique double eccentric collars on both ends of inner ring, perfectly lock forward and reverse rotation, completely solve slipping failure of single eccentric UEL bearings under frequent forward-reverse switching.
Extra-wide symmetric inner ring greatly increases contact area with shaft, improves load bearing capacity and anti-wear performance compared to standard UC narrow inner ring bearings.
Triple-layer composite 3S seal (NBR rubber + multi-lip + steel flinger), multi-stage barrier against mud, sand, crop powder and rainwater, longer service life in harsh field working conditions.
Spherical outer ring self-aligning design (±2° angular compensation), eliminates abnormal noise and premature raceway spalling caused by housing assembly deviation.
Pre-filled long-life lithium complex high-temperature grease, built-in external zerk fitting for periodic re-lubrication; full hardness, noise & vibration inspection before shipment, stable mass production supply.
FAQ
Q1: Can you provide custom bearings?
Yes, we support OEM and custom production based on your drawings, samples, or technical requirements.
Q2: What is the delivery time?
Standard models: 5–10 working days. Custom products: depending on specifications and order quantity.
Q3: What is the difference between UH, UC, UEL and UE series insert bearings?
UH = Double eccentric collars (both sides, bidirectional anti-slip for forward/reverse rotation); UC = Single setscrew lock; UEL = Single eccentric collar (only one rotation direction); UE = Concentric split collar (360° uniform clamping). UH is the best choice for frequent forward-reverse switching equipment.
