What is the purpose of non-standard agricultural machinery bearings

Non standard agricultural machinery bearings refer to bearings that are not designed in a standardized manner and are customized and produced according to the special working conditions, dimensions, or functional requirements of agricultural machinery. It has a wide range of applications and mainly solves special needs that standard bearings cannot meet, including the following scenarios:

1、 Core purpose

1. Adapt to special working conditions

When operating agricultural machinery with heavy loads or impact loads (such as plowing and harvesting), bearings need to withstand high impact forces (such as tractor suspension systems).

Example: Customize to increase the inner diameter of bearings, increase the number of rollers, and enhance load-bearing capacity.

In high dust environments, farmland dust and straw debris are prone to enter bearings, leading to wear and tear.

Solution: Add sealing structures (such as double lip seals), use dust covers or labyrinth seals.

Equipment such as rice harvesters and transplanters that come into long-term contact with muddy water and corrosive environments require bearings to be rust resistant and corrosion-resistant.

Application: Made of stainless steel material, galvanized or coated.

2. Special dimensions and installation requirements

When renovating old agricultural machinery or adapting imported equipment with non-standard shaft diameter/aperture, the shaft diameter does not match the standard bearings.

Example: Customize a bearing with an inner diameter of 120mm (non-standard size) to replace the original 110mm standard bearing.

Due to space limitations, the structure of agricultural machinery is compact and requires reducing the size of bearings or adjusting the shape (such as flat design).

Application: Customized ultra-thin bearings and shaped bearings (such as non-circular inner rings).

3. Special functional requirements

Low noise combine harvesters, seeders, and other equipment that require silent operation to reduce bearing vibration noise.

Technology: Optimize the shape of the raceway and use high-precision retainers.

High speed rotating fans, water pumps, and other components require bearings to support high-speed operation (such as speeds>5000rpm).

Design: Add lubrication grooves, use ceramic balls or high-speed grease.

Long life continuous operation equipment (such as grain dryers) requires bearings to operate for a long time without any faults.

Material: High temperature bearing steel and strengthened heat treatment process are used.
