• Ball Bearings

SLF produce diverse types of ball bearings, whose outer diameters lie in the range of 32 to 1600 mm. All of products fulfil the most stringent requirements of the standards that are in line with DIN and ISO.

The high precision of SLF ball and roller bearings matches the characteristics of comparable world-renowned ball bearing brands. Ball bearings in almost any ranges can be quoted and delivered upon request. SLF can fit your bearing requirement needs with special material, special lubrication, special heat treatment, special backlash and higher levels of precision.
SLF produce high quality thin section bearings for the semiconductor, scientific and robotic industries.

Product groups of our production range:

• Cylindrical roller bearings

When it come to cylindrical roller bearings, at SLF we produce only the highest quality and precision. Cylindrical roller bearing come in a verity of styles and sizes. They range from 30 to 1600mm We manufacture these bearing in standered and specialy materials, special lubrication, special heat treatment and higher levels of precision are produced in single-row, double-rowed, multiple-rowed and fully complement versions, with a wide range of radial load-bearing capacity SLF offer multiple types of cage and roller materials

• Self-aligning ball bearings and self-aligning roller bearings

At SLF we pride ourself in being one of the the word leaders in self-alinging bearings. SLF offer this style bearing with all the same eneeringing, heat treatment, lubrication and material options as our ball and cylindrical bearings are two-rowed bearings with two tracks on the inner ring, and one common spherical track in the outer ring specially produced for bearing-related scenarios involving larger shaft deflections or shaft displacement version with cylindrical and cone-shaped bore hole
