Precision ball bearings - Import export

Steel and stainless steel precision balls applications are limitless (bearings, control balls, screw balls, runner balls…).

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.

Marteau & Lemarie ball specialists since 1922, selling all types of industrial balls on the market: Our company is renowned for the quality of its precision balls and also supplies polishing and grinding balls. Our different type of precision balls include: precision steel, stainless steel and plastic balls, and other precision balls (tungsten carbide, ceramic, glass, bronze and brass balls). Precision steel and stainless steel balls are defined by their nominal diameter, the raw material from which they are made and by their degree of precision. Grinding & polishing balls we stock mainly steel balls, stainless steel balls and glass balls. Our technical sales team is at your disposal for any further information and requests for quotes. So don't hesitate to contact us.

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.

Steel housing. Nitrile rubber seal. Preloaded highaccuracy bearings with a 60° thrust angle. The bearings accept both radial and axial forces from both directions. Due to their preload, the angular contact ball bearings provide a high level of stiffness, excellent concentricity, precise tool positioning and repeatability. The integrated lowfriction seal effectively keeps dirt away from the bearing, thereby ensuring excellent operating safety and a long service life. The bearing friction coefficient Mrl is a reference value. The moment of inertia corresponds to that of the rotating inner ring. The limiting speeds are applicable after grease is applied. Technical data All bearings are supplied ready for mounting with lubricating grease type KE2P35 acc. to DIN 51825. Housing and shaft tolerances correspond to roundness tolerance class IT2 and perpendicularity tolerance class IT4.

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.
