Differences & Selection Guide for Servo Bearing and Standard Bearing
|
Item |
Standard Motor Bearings |
Servo Motor Bearings |
|---|---|---|
|
Design Orientation |
Built for simple, steady and continuous rotary operation |
Engineered for dynamic, high-precision and responsive motion control |
|
Rolling Element (Ball) |
Adopts steel balls with large rolling friction, low precision and poor anti-fatigue performance. Prone to abrasion under frequent variable-speed operation. |
Adopts ceramic balls featuring ultra-low friction, high hardness and light weight. It delivers smoother rotation, less heat generation and excellent wear resistance for dynamic working conditions. |
|
Cage Structure & Material |
Equipped with iron cages, featuring high rigidity but poor toughness. It causes large running noise, easy friction and deformation during frequent start-stop operation. |
Adopts PA46 polymer cages with good toughness, low noise and excellent lubricant retention. It avoids friction abrasion, ensures stable operation and adapts to frequent dynamic movement. |
|
Lubrication & Performance |
General lubricant with basic friction control, limited environmental adaptability |
Custom NLGI 3 grease with ultra-low torque, anti-fretting, low-temperature stability and low vibration |
|
Working Adaptability |
Suitable for constant speed, long-duration steady operation |
Supports frequent start-stop, instant acceleration and intermittent micro-vibration operation |
|
Operational Advantages |
Satisfies conventional low-precision running demands |
Higher positioning accuracy, faster response and better long-term durability |
|
Applicable Scenarios
|
Conventional industrial transmission equipment; stable room-temperature working conditions; no strict requirements on positioning accuracy and motion feedback |
CNC machines, robotic arms and precision automated lines; low-temperature or micro-vibration working environments; scenarios requiring low noise, zero jitter and long service life |
Applications
The advantage of servo motors is precise positioning control, so they are widely used in the control of industrial robots and precision machinery.

FAQ
Q1:What application areas do your products mainly involve?
A:Our bearings application felds mainly include motors, water pumps, household appliances, automoblles, motorcycles, power tools, engraving machines, reducers, machine tools, CNC machining centers, textile machinery, woodworking machinery, etc.
Q2:Can you make customized products?
A:Yes, we can customize products according to customer needs,develop and produce products according to drawings or samples provided by customers. We also have our own brands of HXB and YJB.
Q3:What's the warranty period?
A: The warranty period for all bearing products is one (1) year starting from the date of formal acceptance and receipt of goods by the Buyer.
Q4: Why are low-noise and low-vibration performances critical for servo bearings?
A: Precision industrial equipment such as CNC systems and robotic arms has strict requirements for operational stability. Adopting precise structural matching and low-friction lubrication, our bearings achieve ultra-smooth rotation. They reduce operating noise and vibration, eliminating equipment resonance, positioning jitter and machining errors, and greatly improving servo motion control accuracy and stability.
Q5: What longevity benefits do servo bearings have compared with standard motor bearings?
A: The exclusive custom grease possesses excellent thermal stability and anti-oxidation capability. It effectively avoids lubricant deterioration, dry-out and failure during prolonged high-speed operation. Servo bearings deliver 1.5 times longer service life under high-temperature conditions than conventional bearings, helping prolong equipment maintenance intervals and reduce malfunction risks caused by degraded lubrication.
