Spherical Roller Bearing 23130MB W33 150×250×80mm for Industrial Machinery

The Spherical Roller Bearing 23130MB W33 is engineered to withstand extremely heavy radial and shifting axial loads in both directions. Featuring a robust, inner-ring guided machined brass cage (MB) and integrated relubrication features (W33), it excels at maintaining optimal performance despite severe shaft misalignments or heavy structural deflections.

• Model: 23130MB W33
• Inner Diameter (ID): 150 mm
• Outer Diameter (OD): 250 mm
• Width: 80 mm
• Structure: Spherical Roller Bearing (Double Row)
• Material: High-grade Chrome Steel (GCR15 / 52100)
• Cage Type: MB (Machined Brass Cage, Inner-Ring Guided)
• Lubrication Feature: W33 (Outer Ring Groove and 3 Lubrication Holes)

• Machined Brass Cage (MB): Two-piece inner-ring guided brass retainer provides superior strength, impact resistance, and low friction under severe conditions.
• W33 Relubrication Feature: Equipped with a circumferential oil groove and three lubrication holes in the outer ring for effortless grease replenishment.
• Exceptional Self-Alignment: Smoothly counteracts misalignment and shaft deflections with zero compromise to temperature stability or friction ratings.
• Heavy-Duty Construction: Thrives in high-vibration, shock-heavy, and high-load environments that would prematurely wear out standard steel-cage bearings.
• Custom Clearances: Offered in a broad selection of radial internal clearance grades (CN standard, C3 loose, C4 extra loose) tailored to operating temps.

• Raw material inspection
• Precision machining process
• Heat treatment control
• Clearance & rotation testing
