Linear roller block and rail system

Product catalog summary
Specifications:
The document provides detailed dimensions for the SB-LGB linear guide blocks, including carriage and railway dimensions for models SB-LGB15, SB-LGB20, and SB-LGB30. Tolerances for height are specified as ±0.20mm, with higher accuracy available upon request.
Load Capacity:
The load capacity and life calculation for the SB-LGB system are outlined, with specific conditions affecting system life such as vibration, speed, acceleration, and environmental cleanliness. Maximum load and moment capacities are provided for each model.
Adjustment Procedures:
Instructions are given for adjusting the eccentric roller preload on the SB-LGB carriage block, emphasizing the importance of not overloading to maintain system life. The load should be applied in the direction of the fixed rollers.
Protective Features:
The SB-LGA linear carriage block includes protective end caps with oil-filled felt wipes for reduced friction and corrosion resistance. These are easily re-lubricated through an oil port.
Operating Parameters:
The system supports a maximum linear speed of 10m/s and acceleration of 50m/s², with an operating temperature range of -20°C to +80°C. It is characterized by low friction, high speeds, accurate positioning, and ease of installation.
Company Information:
LM76 is a leader in the linear motion industry, known for its service and engineering excellence, and is the U.S. distributor for SAIBO.

Eccentric (Preload) Adjustment The middle roller on the SB-LGB carriage block is an eccentric (adjustable) roller - 1 and 3 positions are fixed. To adjust eccentric roller preload, do the following: 1. Ensure the concentric (1- fixed rollers) are secured and tightly fastened. 2. Loosen lock nut (2) and insert a hex key wrench into center stud (3) and turn clockwise. The eccentric roller will swing in or out varying its position relative to the shaft- applying more or less pressure (preload) 3. Once the desired preload is achieved, tighten the lock nut (1) while holding the center stud (3) and...

Protective End Caps The SB-LGA linear carriage block features plastic end caps for protection against debris, dust and contaminants. The end caps incorporate spring loaded, oil-filled felt wipes that deliver oil to the shaft/roller interface for reduced friction, heat dissipation and corrosion resistance. The felt wipers are easily re-lubricated by injecting oil into the oil port.
