eCl@ss code: 23050911; UNSPSC code: 31171510 Key specifications and configuration Number of rows: 2 Sealing: Without Bore / Inside Diameter: 160.000 mm Body Outside Diameter: 270.000 mm Width / Thickness: 86.000 mm Tolerance group: Class 5 (P5) Radial internal clearance / preload group: C5 Bearing material: Bearing steel Coating: Without Locating feature: None Key benefits and features precision and stable performance The combination of Class 5 (P5) tolerances and C5 radial clearance supports precise and repeatable operation, benefiting machines that require accurate radial positioning and smooth rotation. Increased load capacity and rigidity A tworow design provides enhanced radial load capacity and stiffness compared with singlerow configurations of similar size, aiding durability in demanding applications. Open, seal design Sealing is not included, reducing friction and allowing straightforward lubrication and inspection in appropriate environments. Durable material Constructed from bearing steel for reliability and predictable wear, suitable for standard lubrication practices. Clearances and fitment Specified bore (160 mm), outer diameter (270 mm) and width (86 mm) support precise shaft/housing integration in compatible assemblies. External alignment ready Locating feature is None, requiring installation within housings or fixtures that provide external alignment and support. Technical suitability and compatibility Fits applications requiring a 160 mm bore on the shaft and a largediameter housing, with precise P5 class accuracy and C5 preload characteristics. Open bearing design is compatible with lubrication schemes that do not rely on integral seals; appropriate cleanliness and maintenance planning are recommended. Applications and use scenarios Scenario 1: Spindle support in CNC milling machines or turning centers where precision, stability, and load handling are essential. Scenario 2: Drive shaft or gearbox input support in heavy machinery, where reliable radial support and rigidity improve overall performance. Scenario 3: Openbearing installations in manufacturing lines that use centralized lubrication and require easy access for inspection, lubrication, or maintenance without seals.
