Product: NN3015K with W33 — Double cylindrical roller bearing Model number: 3182115 Bearing number: NN3015 3015 Dimensions: 75 x 115 x 30 mm Key benefits - High radial load capacity: The double-row NN3015 design delivers greater radial load support and stiffness than single-row bearings, improving reliability in heavy-duty shafts and housings. - Simplified lubrication: The W33 designation provides an outer-ring lubrication groove and hole for convenient relubrication, reducing downtime and extending service life. - Exact fit and easy replacement: Supplied as NN3015K with model 3182115 and bearing number NN3015 3015, so you can match parts precisely for maintenance and replacements. - Space-efficient performance: With compact dimensions (75 x 115 x 30 mm), the bearing fits applications requiring a balance of load capacity and limited envelope size. Core features and function - Type: Double cylindrical roller bearing (NN3015 type) designed primarily to support heavy radial loads on rotating shafts. - Variant: NN3015K with W33 — includes the K variant of the NN3015 family and the W33 lubrication provision as specified. - Application role: Provides radial support and rigidity; commonly used where axial displacement may occur or where separable components are required for assembly and maintenance. Compatibility and installation notes - Size compatibility: Match to shafts and housings designed for a bearing with bore and outside diameter corresponding to 75 x 115 x 30 mm. - Identification: Use model number 3182115 or bearing number NN3015 3015 when ordering to ensure exact compatibility. - Lubrication access: The W33 groove/hole simplifies periodic relubrication — essential for maintaining performance in continuous or heavy-load service. Typical use scenarios - Industrial gearboxes: Supports main shafts where high radial loads and rigidity are required for torque transmission. - Heavy machinery and presses: Serves as a robust radial bearing in rolling equipment, conveyors, or press shafts exposed to continuous radial loading. - Rotating equipment with service access: Ideal where regular relubrication is required via the W33 groove/hole to maintain bearing life in pumps, motors, or drive assemblies. Why choose this bearing - Matches NN3015 specification for reliable replacement and inventory consistency. - Built to provide stable radial support in compact form factors. - W33 lubrication provision lowers maintenance effort and helps preserve bearing performance over time.
