Precision Motion for Diverse Applications

SKF LBCD linear ball bearings provide exceptional performance for automation, CNC machinery, robotics, and linear guide systems. Their ground surface finish and precision tolerances guarantee smooth, accurate motion, improving machine reliability and productivity even in highly dynamic environments.

Flexible Design and Interchangeability

These bearings are DIN ISO 10285 compliant, meaning they are easily interchangeable with other standard linear components. Available in a wide range of bore and outside diameters, mounting configurations, and seal options, the SKF LBCD series allows easy adaptation to various engineering requirements.

Robust and Reliable Operation

Made from high-grade chrome or stainless steel, SKF LBCD linear ball bearings offer durability under tough industrial conditions. Double seals and self-aligning variants help ensure longevity and effective compensation for misalignments, while built-in lubrication supports maintenance and keeps noise levels to a minimum.

FAQs of SKF Linear ball bearings LBCD:

Q: How are SKF LBCD linear ball bearings mounted in machinery?

A: SKF LBCD linear ball bearings are designed for housing-mounted applications. Simply place the bearing into a compatible housing as per the DIN ISO 10285 standard dimensions, ensuring the shaft fits with an h6 tolerance for optimum performance.

Q: What types of applications can benefit from SKF LBCD linear ball bearings?

A: These bearings are ideal for automation systems, CNC machinery, robotics, and linear guides, thanks to their smooth motion, high precision, and robust load-handling capacity of up to 7000 N depending on size.

Q: When should I choose a self-aligning SKF LBCD model?

A: Select self-aligning models when your application may experience shaft misalignment or mounting inaccuracies. These variants compensate for minor misalignments, ensuring consistent linear motion and reducing wear.

Q: Where can I source SKF LBCD linear ball bearings in India?

A: SKF LBCD linear ball bearings are available through authorized distributors, importers, and suppliers across India, ensuring reliable access to genuine products and technical support.

Q: What is the process for re-lubricating SKF LBCD linear ball bearings?

A: Most LBCD bearings are factory pre-lubricated, but re-lubrication is possible. Follow SKFs recommended procedure: use compatible lubricant and supplied lubrication holes or direct application, depending on the bearing configuration.

Q: How does the double seal feature benefit SKF LBCD linear ball bearings?

A: Double seal models help protect the internal mechanism from contaminants, prolonging bearing life and maintaining smooth linear motion, especially in environments exposed to dust and debris.

Q: What are the advantages of the low noise level in SKF LBCD bearings?

A: Low noise operation enhances user comfort and makes these bearings suitable for sensitive environments such as laboratory automation or medical equipment, where quiet running is essential.
