ina hk15162rs

The INA HK1516-2RS (often appended with the standard factory grease suffix L271) is a premium drawn cup needle roller bearing featuring integrated lip seals on both sides. Manufactured by the Schaeffler Group under the INA brand, this open-ended, single-row bearing is designed to support high radial loads within an exceptionally compact footprint.

Technical Specifications

The precise engineering dimensions and performance thresholds for this specific model include:

Metric Feature Specification Value
Under-Roller Bore Diameter (\(F_{w}\)) 15 mm
Outside Diameter (D) 21 mm
Width (C / B) 16 mm
Basic Dynamic Load Rating (\(C_{r}\)) 7,800 N
Basic Static Load Rating (\(C_{0r}\)) 9,800 N
Limiting Speed (Grease) 9,900 rpm
Net Weight ~14 grams


Key Identification Codes

• HK: Drawn cup needle roller bearing with open ends.
• 1516: Identifies the primary dimensions (15 mm internal diameter under rollers, 16 mm width).
• -2RS: Equipped with contact lip seals on both sides to retain grease and protect against contaminants.
• -L271: Standard factory designation for the specific initial grease fill optimized for standard operating ranges.

• The Sizing Logic: The imperial SCE code operates strictly in sixteenths of an inch. The 7 identifies a 7/16" internal bore diameter under the rollers, and the 8 designates an 8/16" (1/2") overall cup width.
• Dimensions: 7/16" (11.113 mm) Inside Diameter × 5/8" (15.875 mm) Outside Diameter × 1/2" (12.700 mm) Width.
• Operating Clearances: Basic dynamic radial load capacity sits at approximately 1,440 lbf (~6,400 N) with a limiting speed ceiling near 23,000 RPM.

• Shaft / Bore Diameter (\(F_{w}\)): 3/8 in (9.525 mm)
• Outside Diameter (D): 9/16 in / 0.5625 in (14.288 mm)
• Width (C): 5/16 in / 0.3125 in (7.938 mm) (Note: Though the total outer shell assembly occupies a 3/8" footprint in some housing calculations, the precise boundary width of the cup is 7.94 mm).
• Basic Dynamic Load Rating (\(C_{r}\)): 3,900 N (870 lbs)
• Basic Static Load Rating (\(C_{0r}\)): 3,950 N (890 lbs)
• Limiting Speed: 25,000 r/min (Allows for much faster rotation than the un-caged S66)
• Weight: 4.42 grams (0.009 lbs)

• Under-Roller Bore Diameter (\(F_{w}\)): 2.0000 inches (50.800 mm)
• Outside Diameter (D): 2.3750 inches (60.325 mm)
• Width (C): 1.0000 inch (25.400 mm)
• Basic Dynamic Load Rating (\(C_{r}\)): 41.5 kN (9,330 lbf)
• Basic Static Load Rating (\(C_{0r}\)): 80.0 kN (17,985 lbf)
• Limiting Speed: 5,100 RPM (Oil lubrication)
• Mass (Weight): ~0.225 lbs (102 g)

• Under-Roller Bore Diameter (\(F_{w}\)): 1.7500 inches (44.450 mm)
• Outside Diameter (D): 2.1250 inches (53.975 mm)
• Width (C): 1.5000 inches (38.100 mm)
• Basic Dynamic Load Rating (\(C_{r}\)): 62.0 kN (approx. 14,000 lbf)
• Basic Static Load Rating (\(C_{0r}\)): 130.0 kN (approx. 29,000 lbf)
• Limiting Speed (Grease): 6,300 RPM
• Mass (Weight): ~0.315 lbs (143 g to 163 g depending on cage variant)
