LMK 20 UU bearing Flange type linear bearing is a type of linear motion bearing with a flange plate.Which is directly fixed to the equipment base through the flange, simplifying the installation structure and improving the load-bearing stability. The main features are as follows: square flanges are distributed parallel to the four corners, providing higher resistance to torsion and suitable for equipment that requires precise positioning.
Core advantages of LMK 20 UU bearing
1. High load-bearing capacity and vibration resistance.
The flange structure increases the load-bearing area, disperses the impact load.And increases the bearing capacity by more than 30% compared to ordinary linear bearings.
2. Installation convenience
The flange is directly fixed with bolts, eliminating the need for additional bearing seats and reducing assembly complexity and costs.
3. Space optimization
Compact design reduces equipment space occupation, especially suitable for precision instruments or compact machinery.
4. Low friction and high precision
Internal multiple rows of steel balls rolling friction (friction coefficient as low as 0.001) ensures smooth high-speed movement.
5. Environmental adaptability
Sealed design for dust and dirt prevention, some models support operation in liquid environments.
Key parameters for selection
Axis diameter tolerance: Match with H7 level tolerance axis or imperial axis.
Verticality of flange installation surface: affects motion accuracy and requires strict testing.
Load and speed: For heavy loads, choose the extended type, and for high speeds, use quenched steel shafts.
Key points for installation and maintenance of lmk 20 uu bearing
Installation steps: Clean the guide rail → Pre tighten the flange bolts → Tighten step by step to avoid overloading.
Lubrication cycle: Regularly inject lithium grease or oil for lubrication, and shorten the cycle in high-temperature environments.
Wear and tear inspection: Monitor for abnormal noise or motion jamming, and replace the sealing ring in a timely manner.
