Wholesale Standard Type Linear Ball Bearing Manufacturer
As a Wholesale Standard Type Linear Ball Bearing manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Shanghai Yinin Bearing & Transmission Company is a China-based manufacturer and supplier of standard type linear ball bearings, offering the LM, LMB, and LME series. With over 20 years in the bearing industry, we combine in-house manufacturing with a comprehensive quality system to deliver reliable linear motion components for global automation, machinery, and industrial equipment applications.
Our standard type linear ball bearings are designed for high-precision linear guidance, providing smooth motion, low friction, and long service life. We supply wholesale quantities to distributors, OEMs, and project-based buyers, supporting both standard and customized requirements.
Product Range and Applications
We manufacture three main series of standard type linear ball bearings, each tailored to specific load, speed, and installation needs. All are available in metric sizes and can be supplied with seals or shields as required.

Engineering and Quality Assurance
Our standard type linear ball bearings are manufactured from high-grade bearing steel (typically GCr15 or equivalent) with precision-ground raceways and hardened balls. We apply strict process control from raw material inspection to final assembly, ensuring dimensional accuracy and consistent performance.
Each batch undergoes comprehensive testing, including radial clearance, surface roughness, and noise/vibration checks. We follow international standards such as ISO and GB/T, and we can provide inspection reports upon request. Our quality system is backed by our in-house R&D and QC teams, with 12 technicians overseeing production.
Configuration and Customization
While we offer standard types, we also support customization to meet specific application requirements. Options include:
- Different materials (chrome steel, stainless steel, or hybrid)
- Seals or shields for contamination protection
- Special tolerances or preloads
- Non-standard sizes or mounting features
Our engineering team works with you to define the correct bearing for your load, speed, and environmental conditions. We provide technical advice on shaft hardness, housing fit, and lubrication to maximize bearing life.
Integration and Installation Support
Standard type linear ball bearings are typically used with hardened and ground shafts. We can supply matching shafts or recommend suitable materials. For automated assembly lines, we offer bearings that are ready for press-fit installation, with clear mounting instructions.
Our team provides installation guidance to prevent misalignment and premature failure. We also advise on proper lubrication intervals and maintenance schedules, helping you reduce downtime and extend equipment life.
Information We Use to Configure Your Solution
To prepare an accurate quotation and technical proposal, please provide the following details:
- Required series (LM, LMB, LME) and shaft diameter
- Operating load (radial/axial) and expected life
- Travel speed and acceleration
- Environmental conditions (temperature, dust, moisture)
- Mounting arrangement (horizontal/vertical)
- Quantity and target delivery schedule
With this information, we can recommend the optimal bearing type, material, and sealing option, and provide a competitive wholesale price.
Packaging and Delivery
We package bearings individually in rust-proof paper or plastic tubes, then in export-grade cartons or wooden cases to prevent damage during transit. Our warehouse ensures prompt dispatch, with in-stock items shipped within 3 working days. For bulk orders, we coordinate logistics to meet your project timeline.
Frequently Asked Questions
What is the difference between LM, LMB, and LME series?
LM series is the standard metric type with a cylindrical outer diameter. LMB series is more compact and lightweight. LME series follows European dimensions and is often interchangeable with other brands. We can help you select based on your shaft size and space constraints.
Can you provide stainless steel linear ball bearings?
Yes, we offer stainless steel versions for corrosion-resistant applications, such as in food processing or medical equipment. Please specify your requirement, and we will confirm availability and lead time.
What is the minimum order quantity for wholesale?
Our standard minimum order is 100 pieces per size, but we can accommodate smaller trial orders for evaluation. For large volume projects, we offer tiered pricing.
How do you ensure quality consistency across large orders?
We implement in-process inspections and final testing on every batch. Our quality control team follows documented procedures, and we maintain traceability from raw material to finished product.
Do you provide technical support for bearing selection?
Absolutely. Our engineers can review your application parameters and recommend the most suitable bearing type, including load ratings and life calculations. We also provide installation and maintenance guidance.
