L44649 Bearing Size: The Ultimate Guide

The L44649 is a deep groove ball bearing with a 12mm inner diameter, a 24mm outer diameter, and a 6mm width. This bearing is commonly used in a variety of applications, including:

• Automotive engines
• Electric motors
• Pumps
• Appliances
• Power tools

The L44649 is a metric bearing, which means that its dimensions are specified in millimeters. The bearing's inner diameter is the diameter of the shaft that the bearing will fit on. The bearing's outer diameter is the diameter of the housing that the bearing will fit into. The bearing's width is the distance between the bearing's inner and outer races.

Bearing Materials

The L44649 is typically made from chrome steel, which is a type of steel that is hardened and tempered to increase its strength and durability. The bearing's races are made from inner ring material, which is a type of steel that is hardened and tempered to increase its resistance to wear. The bearing's balls are made from SAE 52100 steel, which is a type of steel that is hardened and tempered to increase its hardness and wear resistance.

Bearing Lubrication

The L44649 is typically lubricated with grease, which is a type of lubricant that is made from a base oil and a thickening agent. The grease is applied to the bearing's races and balls, and it helps to reduce friction and wear.

Bearing Installation

The L44649 can be installed by pressing it into the housing. The bearing should be pressed into the housing until it is seated against the shoulder. The bearing should not be pressed too far into the housing, as this can damage the bearing.

Bearing Maintenance
