Slit Oilless Bronze Bushings for Hydraumatic Applications, Material: CuSn8P (Phosphor Bronze), Size: 40x44x40 (BMZ 4040) are components designed for use in hydraulic systems where lubrication oil is not readily available or desired. These bushings feature a slit design that allows for slight expansion or contraction, accommodating minor misalignments or shaft movements while maintaining a secure and wear-resistant fit. The CuSn8P (Phosphor Bronze) material is chosen for its excellent corrosion resistance, high strength, and good wear properties, making it suitable for demanding hydraulic applications. The 40x44x40 size (BMZ 4040) indicates the outer diameter, inner diameter, and length of the bushing, respectively.

RoHS compliant. • Wrapped Bronze Bushing CuSn8 material made of solid bronze strip with indents for lubrication. • Good wear resistance, suitable for rough conditions.

Bronze bushing BMZ 4040 size is made of Bronze and has dimensions of 40mm inner diameter by 44mm outer diameter and a length of 40mm. Low maintenance because it has lubrication depots. High load-bearing capacity and strength with low wear, suitable for rough use, corrosion-resistant Bronzes with lubrication deposits. Low maintenance. Corrosion-resistant. For high loads.

Diamond solid self-lubricating oil-free bearing

Low-maintenance wrapped bronze sliding bearing, with lubrication pockets

Good load capacity and stability at low abrasion, suited for operation, corrosion-resistant.

Slit Oilless Bronze Bushings For Hydraumatic CuSn8P 40x44x40 BMZ 4040 Size 

VIIPLUS provides hydraulic system users with a complete set of sliding bearing solutions.The products are: gear pump aluminum seat assembly, shaft sleeve, side plate;Distribution plate, return plate and shaft sleeve for vane pump and plunger pump;Cylinder sleeve and so on.We offer high quality Oilless Bearings, Bushings.Bronze Slit Bushing, 40x44x40mm BMZ 4040 Size bronze bushing with tin bronze alloy CuSn8P DIN 17662. CW453K Wrapped Bronze Bearing:BK-090, BRM10, COB-090, MBZ-B09, PRM, PRMF, SERIE SBA, SERIE SBB, WB700, WF-WB 700 MADE IN CHINA.

The bronze bushing is made of tin bronze CuSn8P. The surface is stamped with diamond oil sockets, which are stored to save oil. It has good anti-fatigue, anti-erosion anti-abrasion and durability. The products are often used under conditions of high load and low running speed, e.g. B. in agricultural, construction and engineering machinery.Bronze bearing, with special formula of high density copper alloy as the matrix, the surface can be rolled according to user's requirements diamond or hemispherical oil boots, oil groove.With high density and high bearing pressure, good wear resistance, long life and other advantages, to replace the traditional copper casting sets, can reduce the size of our machinery, reduce cost, FB090 to widely used in hoisting machinery, construction machinery, automobile tractor chassis, machine tool industry and mining machinery, also can be made into bearing, flanged bushes, thrust washers, and qiu bowl and so on.

Chemical Compositions

The installation

The bearing shall be pressed into the bearing seat of tolerance H7.Bearing bore tolerance H9.
Shaft - bearing fit
For bearing with tolerance H9, we recommend e7 or f7 as the tolerance for the shaft.If h axis is selected, it is recommended that the bearing inner diameter tolerance be F7.
lubrication Bushing
Lubrication shall be achieved by passing the shaft or radial through the bearing housing.All common grease types or oils can be used.
Non-standard custom
We can recommend the appropriate size, shape, and shape or length upon request.Please contact us for quotation or more information.
