The L48548L/48510 tapered roller bearing is engineered to provide reliable performance in trailer applications, effectively supporting both radial and thrust loads. This bearing set combines the inner ring (cone) and the outer ring (cup) into a single unit, featuring the following specifications:

Key Specifications

• Inner Ring (Cone) Part Number: L48548L

  • Inner Diameter (d): 34.925 mm (1.375 inches)
  • Width (B): 18.288 mm (0.720 inches)

• Outer Ring (Cup) Part Number: 48510

  • Outer Diameter (D): 65.088 mm (2.5625 inches)
  • Width (C): 18.034 mm (0.710 inches)

• Overall Width (T): 18.034 mm (0.710 inches)

Design and Functionality

Tapered roller bearings are composed of four critical components:

• Cone (Inner Ring)
• Cup (Outer Ring)
• Tapered Rollers (Rolling Elements)
• Cage (Roller Retainer)

These bearings are engineered to efficiently manage both axial and radial loads between rotating and non-rotating components. The steep angle of the cup enhances its ability to handle axial thrust loads.

Applications

• Trailers: Ideal for trailer wheel hubs, ensuring smooth and reliable operation.
• Moderate- to low-speed automotive and industrial applications
• Aircraft wheels
• Agricultural equipment
• Idler rollers
• Side-delivery hay rakes

Design Attributes

• TS Design: Includes a seal pressed onto the cone rib OD, with one seal lip engaging the housing bore and the other sealing against the cup face.

Dimensions

• Inside Diameter (d): 34.925 mm (1.375 inches)
• Outside Diameter (D): 65.088 mm (2.5625 inches)
• Width (B): 18.034 mm (0.710 inches)

Product Benefits

• High Load Capacity: Efficiently supports combined radial and axial loads, ensuring performance under heavy-duty conditions.
• Durability: Constructed from high-quality materials for reliable longevity and operational integrity.
• Versatility: Suitable across a spectrum of applications, guaranteeing dependable performance in diverse industries.

Operating Conditions

• Temperature Range: Effective performance typically ranges from -30°C to 120°C, contingent on the lubricant type.
• Lubrication: Compatible with various lubricants, facilitating smooth running and prolonged service life.

The L48548L/48510 tapered roller bearing stands as an optimal choice for trailer applications necessitating steadfast performance and durability. Its robust design and meticulous engineering ensure enduring efficiency, maintaining the reliability and safety of trailer wheels under diverse operational demands.

roller bearing description

The inner and outer ring raceways are segments of cones and the rollers are tapered so that the conical surfaces of the raceways, and the roller axes, if projected, would all meet at a common point on the main axis of the bearing. This geometry makes the motion of the cones remain coaxial, with no sliding motion between the raceways and the outside diameter of the rollers.

This conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical (ball) bearings, which have point contact. The geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs.

The rollers are stabilized and restrained by a flange on the inner ring, against which their large end slides, which stops the rollers from popping out due to the "pumpkin seed effect" of their conical shape.

The larger the half angles of these cones the larger the axial force that the bearing can sustain.

Tapered roller bearings are separable into a cone assembly and a cup. The non-separable cone assembly consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers. The cup is simply the outer ring. Internal clearance is established during mounting by the axial position of the cone relative to the cup, although preloaded installations without clearance are common.

Metric tapered roller bearings follow the designation system defined by ISO 355.
