Precision SKF LBCD 20 D 2LS closed linear bearing with double seal AI-Powered Review

Technical Description - SKF LBCD 20 D 2LS Linear Bearing

The SKF LBCD 20 D 2LS is a self-aligning, closed-type linear ball bearing engineered for shafts with a diameter of 20 mm. It features the D-type self-aligning design, which compensates for minor misalignments in the guide system, and 2LS double lip seals on both sides, ensuring effective protection against dust and contaminants. This design extends bearing life and reduces the need for frequent lubrication.

Key Features and Benefits:

• Self-aligning design - compensates for misalignments in linear shafts.

• 2LS sealing - dual lip seals protect against dust and particles, ensuring long service intervals.

• Factory pre-lubricated - supplied with SKF premium grease for long-lasting performance.

• Low friction operation - optimized seal design minimizes resistance.

• Closed bearing construction - ideal for industrial environments requiring reliable sealing.

• Industrial applications - perfect for CNC machines, linear motion systems, automation, and robotics.

Technical Specifications (typical values):

• Bore (Fw): 20 mm

• Outer diameter (D): ~32 mm

• Length (C): ~45 mm

• Lubrication: factory-greased (SKF LGEP2)

• Max speed: up to ~5 m/s

• Seal type: 2LS (double lip seals)

• Option: stainless steel HV6 variant available for harsh environments

Installation and Use

• Ensure shafts and housings are clean before mounting.

• Factory pre-lubrication means no immediate re-greasing is required.

• For demanding environments (high humidity, chemicals), stainless steel variants can be selected.

• Shaft tolerance recommendation: h6.

❓ FAQ (EN)

Q: What does SKF LBCD 20 D 2LS mean?
A: It is a closed, self-aligning linear ball bearing for Ø20 mm shafts, with double lip seals on both sides for protection.

Q: Is the bearing self-aligning?
A: Yes - the D-type design provides self-alignment, compensating for small shaft misalignments.

Q: Does it require frequent lubrication?
A: No - thanks to factory pre-lubrication and effective sealing, re-greasing is rarely needed under normal conditions.

Q: What are the main applications?
A: CNC machinery, automation systems, robotics, precision equipment, and linear motion guides.

Q: Is a stainless steel version available?
A: Yes - the HV6 variant is available for harsh environments or where corrosion resistance is critical.
