IKO 81111 MPB

IKO 81111 MPB Thrust Bearing Description The IKO 81111 MPB is a single-direction cylindrical roller thrust bearing designed to accommodate heavy axial loads. This bearing is separable, meaning the shaft washer, housing washer, and roller and cage assembly can be mounted independently. Its robust design with a machined brass cage ensures high reliability and a long service life in demanding industrial machinery. The compact axial height makes it ideal for applications where space is a constraint. Specifications Manufacturer: IKO Type: 81111 MPB Category: Cylindrical Roller Thrust Bearing Bore Diameter: 55 mm Outside Diameter: 78 mm Height: 16 mm Cage Material: Machined Brass Dynamic Load Rating: 68.7 kN Static Load Rating: 251 kN Application This type of bearing is commonly used in applications such as machine tool spindles, gearboxes, extruders, and lifting equipment where high axial stiffness and load capacity are required. Country of Origin This product is manufactured by IKO in Japan. CO2 Impact Opting for this pre-owned IKO bearing prevents the emission of approximately 0.44 kg of CO2, which would have been generated during the production of a new one. This saving is comparable to the emissions from driving a standard car for over 2 kilometers. Availability This item is in stock and ready for immediate dispatch.

FAQ What does the ‘MPB’ suffix signify for the IKO 81111 bearing?The ‘M’ indicates a machined cage, and ‘PB’ specifies that the material is brass. This type of cage offers high strength and is suitable for high-speed operation and high temperatures compared to standard steel or polyamide cages. Is this bearing suitable for high-speed applications?Yes, the machined brass cage makes it suitable for higher speeds than bearings with pressed steel cages. However, for any specific application, it is crucial to check the limiting speeds in the manufacturer’s technical documentation, considering the lubrication method used. What is the correct lubrication procedure for this thrust bearing upon installation?This bearing should be lubricated with either grease or oil. For grease lubrication, the bearing should be filled with a suitable high-quality bearing grease. For oil lubrication (e.g., in a gearbox), ensure that the oil flow is sufficient to cool and lubricate the rolling elements, especially at higher speeds. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
