L44649 bearings are typically manufactured from high-quality bearing steel, such as AISI 52100. The bearing rings are hardened and ground to ensure precision and durability. The rollers are also hardened and ground to provide optimal load distribution and minimize wear.
L44649 bearings find applications in a wide range of industries, including:
They are commonly used in applications that involve heavy loads, high speeds, and demanding operating conditions.
L44649A bearings have an additional seal on one side, providing better protection against contamination.
A general-purpose lithium-based bearing grease is recommended.
The frequency of relubrication depends on the application. Consult your bearing manufacturer's instructions.
No, L44649 bearings are not designed for water environments.
Generally, the maximum operating temperature is around 120°C (250°F). However, refer to the manufacturer's specifications for specific limits.
Common causes include improper lubrication, contamination, misalignment, and overloads.
