Agricultural machinery bearing purchase

**Agricultural Machinery Bearing Purchase Guide** Home > Bearing Knowledge > Agricultural Machine Bearing Purchase This article was published on June 28, 2014 by China Bearing Network. Bearings are essential components in agricultural machinery, such as tractors, engines, and threshers. They support rotating or moving parts and play a critical role in ensuring smooth operation. When purchasing bearings, understanding the bearing code system is key to selecting the right part. Most commonly used bearings have a standard code format, typically consisting of seven digits. The first digit usually indicates the type, while the last two digits represent the inner diameter. For example, in the code 7002136 (used for a 135 series diesel engine shaft), the "36" represents the inner diameter (36 × 5 = 180 mm), "1" refers to the narrow width series, "2" indicates a cylindrical roller bearing, "00" shows no ribs on the outer ring, and "7" means it’s a light-duty bearing. Understanding these codes helps farmers and operators make accurate purchases without confusion. Here’s how to interpret inner diameters: - Bearings with an inner diameter below 9 mm are marked with the last digit representing the actual size. For example, 18 means 8 mm. - Bearings with an inner diameter between 10–17 mm use fixed numbers. For instance, 100 means 10 mm, 201 means 12 mm, and so on. - Bearings with an inner diameter from 20–480 mm are calculated by dividing the number by 5. So, 204 would be 20 ÷ 5 = 4 mm (wait—this is actually 20 mm). - Bearings larger than 500 mm use a fractional notation, where the denominator is the inner diameter. For example, 30031/560 means the inner diameter is 560 mm. By learning these rules, agricultural machine users can confidently identify and purchase the correct bearings. If you're unsure about a specific bearing, always refer to the manufacturer's catalog or consult a bearing expert. Proper selection ensures better performance, longer life, and fewer mechanical failures.
