The L44643L/44610 tapered roller bearing, also known as 44600LA, is specifically designed to deliver robust performance in trailer applications, providing reliable support for both radial and thrust loads. This bearing set includes both the inner ring (cone) and the outer ring (cup) in a combined unit, with the following specifications:

Key Specifications

• Inner Ring (Cone) Part Number: L44643L

  • Inner Diameter (d): 25.400 mm (1 inch)
  • Width (B): 14.732 mm (0.580 inches)

• Outer Ring (Cup) Part Number: L44610

  • Outer Diameter (D): 50.292 mm (1.980 inches)
  • Width (C): 14.224 mm (0.560 inches)

• Overall Width (T): 14.732 mm (0.580 inches)

Design and Functionality

Tapered roller bearings consist of four interdependent components:

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

These bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

Applications

• Trailers: Ideal for use in trailer wheel hubs, ensuring smooth and reliable performance.
• Moderate- to low-speed automotive and industrial applications
• Aircraft wheels
• Farm implement wheels
• Idler rollers
• Side-delivery hay rakes

Design Attributes

• TS Design: Features a seal pressed onto the cone rib OD. One seal lip operates in the housing bore while the other seals against the cup face.

Dimensions

• Inside Diameter (d): 25.400 mm (1 inch)
• Outside Diameter (D): 50.29 mm (1.98 inches)
• Width (B): 14.22 mm (0.56 inches)

Product Benefits

• High Load Capacity: Efficiently supports both radial and axial loads, enhancing performance under heavy loads.
• Durability: Manufactured from high-quality materials for reliable performance and long service life.
• Versatility: Suitable for a wide range of applications, ensuring reliable performance across different industries.

Operating Conditions

• Temperature Range: Typically operates effectively within -30°C to 120°C, depending on the type of lubricant used.
• Lubrication: Compatible with various greases and lubricating oils, ensuring smooth operation and extended service life.

The L44643L/44610 tapered roller bearing is an ideal choice for trailer applications requiring dependable performance and durability. Its robust construction and precise design ensure long-lasting, efficient operation, making it perfect for ensuring the reliability and safety of your trailer wheels.

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.
