Product Parameters
1. Nominal shaft diameter and dimensional parameters
The nominal shaft diameter range is 5mm to 60mm. Common models include LME5UU (5mm), LMH12OU (12mm), LME30UU (30mm), etc. The accuracy of the shaft diameter directly affects the fit clearance between the bearing and the guide rail.
Tolerance Specifications Inner Diameter: Permissible deviation ranges between ±0.008mm and ±0.016mm (e.g., LME series maintains a +8/0μm tolerance). Outer Diameter: Unidirectional tolerance spanning 0/-10μm to 0/-16μm (as seen in LMB6LUU's 0/-10μm specification). Length: Standard tolerance of ±300μm (demonstrated by LME5UU model).
Flange Dimensions Diameter : Varies from 38.1mm to 112mm (LMB6LUU adopts the minimum 38.1mm). Thickness (t): Ranges 6.35–17mm (LME5UU implements a reduced 5mm thickness)
2. Rated load and dynamic performance
- Rated load: Dynamic load : 28N to 7550N (e.g. LME5UU dynamic load is 206N, LMEF0LUU dynamic load is 7550N). Static load : 22N to 20000N (e.g. LME5UU static load is 265N, LME60LUU static load is 20000N).
- Movement speed: upper limit linear speed: 1m/s to 6m/s (continuous operation). Upper limit rotation speed: 0.8m/s to 1.5m/s (short-term operation).
3. Structural type and installation form
- Flange type: Round flange: suitable for scenarios with large radial loads (such as LME series). Method Lan: Suitable for scenarios with high axial loads (such as LMEK series). Extended flange: suitable for scenarios that require a larger installation area (such as LMB6LUU with rectangular flange).
- Retainer material: Nylon Retainer: Suitable for low-speed, light load scenarios (such as LM8SUU). Metal cage: suitable for high-speed and heavy-duty scenarios (such as LME30UU).
Product Features And Applications
1. Product characteristics of linear bearing flanged aluminum slides
- Compact structure: It adopts an integrated structure of linear bearings and flange shaft sleeves. Compared with the combination of linear bearings and separately made flanges, it has the advantages of low price, short delivery time, and stable quality. The structure is more compact and can achieve a compact design that maintains load resistance performance.
- Strong load-bearing capacity: The flange type design can better withstand and distribute loads, allowing the bearing to maintain stable performance even under large loads.
- Easy installation: Flanges are generally divided into three types: circular, square, and chamfered. They can be installed using screws, making installation easier.
Low Friction & High Precision The point-contact design between the ball and the linear axis minimizes friction forces, enabling high-accuracy motion and ensuring smooth, precise linear movement.
Corrosion Resistance & Lightweight Construction Constructed from aluminum alloy, the substrate combines lightweight properties with corrosion resistance, making it adaptable to diverse operational environments.

Thoughtful Service, Worry Free After-sales Service
- Quality control system
We strictly adhere to the ISO9001 quality management standard, setting up multiple quality inspection checkpoints at every stage from raw material screening to production and processing, and finally to finished product delivery. For example, on the bearing production line, we adopt a three inspection system (self inspection, mutual inspection, and special inspection) to ensure that the accuracy error of each product does not exceed 0.01mm.
- Technical team strength
The technical department is composed of more than 20 engineers with over 10 years of experience. They are not only proficient in traditional mechanical design, but also able to provide customized solutions based on the actual working conditions of the customer's workshop, such as high temperature, high humidity and other special environments. Last year, we improved the dust-proof structure of the guide rail for a certain car manufacturer, increasing its service life by 40%.
- After sales guarantee network
Establish a 7 × 24-hour response mechanism and set up 5 spare parts warehouses in major industrial areas in China. When a CNC enterprise in Jiangsu suddenly experienced a guide rail failure, our engineers arrived at the site with spare parts within 4 hours and completed the replacement and debugging on the same day, avoiding losses from the customer's production line shutdown.
