Precision ball bearings - Import export

Material: Housing thick steel plate. Tyres steel-wire reinforced elastic solid rubber. Wheel body welded steel. Version: Housing press formed. Reinforced fork, base plate and centre pin. Double ball bearing with hardened shells in the castor head. Precision ball bearings in the wheels. Note: These castors are particularly impact and shock proof and assure a high service life. Wheel axle bolted.

We produce diverse types of ball bearings, whose outer diameters lie in the range of 32 to 1600 mm. All of our products fulfil the most stringent requirements of the standards that are in line with DIN and ISO. The high precision of our 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. We also produce high quality thin section bearings for the semiconductor, scientific and robotic industries. Our portfolio of services also includes the reconditioning of ball bearings.

During the turbo rebuilds, we offer an opportunity to enhance both reliability and performance through turbo upgrades. Our array of turbo upgrades encompasses options such as billet wheels, high-performance bearings and seals, larger turbines, ball-bearing conversions, precision machining of turbocharger housings, turbine blade optimization, meticulous porting and polishing, staggered seals, innovative hybrid solutions, and beyond. It's noteworthy that all of our upgraded turbochargers are furnished with enhanced bearings and seals as a standard feature, and all of this is offered at highly competitive prices.

Idler with precision roller tube and precision groove ball bearing, multiple labyrinth, dust cover, rain cover and grease chamber Support rings and buffer rings Side guiding rollers Holding brackets for lower belt rollers

Housing washer, shaft washer and rolling elements, bearing steel. Cage, steel. Note Axial ball bearings accept high axial loads from one direction but may not be loaded radially. The bearings are separable. This means the bearing parts can be fitted independently of each other. The main dimensions of the axial ball bearing conform to ISO 104 and DIN 711. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. These tolerance classes are standard and are well suited for most applications.

Ceramic bearings Si3N4. Bearing cage PTFE. For most applications Si3N4 is the preferred material for ceramic bearings. Silicon nitride bearings are light, very hard and highly wear resistant. High and ultrahigh performance bearings are used in e.g. aerospace technology, metal production industries (high application temperatures), machine manufacturing, chemical industries (chemically aggresive substances), pharmaceutical and medical industries, semiconductor and biotechnology (clean room enviroments which may not be contaminated by lubricants). On request Special version with PEEK ball cage. Without ball cage.

Inner ring, outer ring and rolling elements, bearing steel. Cage sheet steel. Labyrinth seal sheet steel. Lip seal NBR. Version 2Z = sealed both sides with noncontact labyrinth seals. 2RSR = sealed both sides with contact lip seals. Note Deep groove ball bearings accept high radial and axial loads. Axial loads are absorbed in both directions. The versions 2Z and 2RSR are lubricated for life with a high quality grease. The main dimensions of the deep groove ball bearings conform to DIN 6251. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. The radial internal clearance corresponds to the clearance CN acc. to DIN 6204. These tolerance classes are standard and well suited for most applications.

Housing steel. Cage plastic. Balls steel. Note The linear ball bearings correspond to series 3 of ISO 10285. With doublesided seal. The linear ball bearings have a plastic cage which results in quiet and outstanding running properties. With flange for direct mounting on the housing. Linear ball bearings with doublesided seal should be greased before installation. The specified load ratings apply with the use of hardened and ground shafts. Precision guide shafts 21595. Fastening screws 07160.
