Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'куст' (bush/shrub).
- The technical Russian equivalent is often 'втулка' (vtulka) or 'вкладыш' (vkladysh).
- Do not confuse with 'bush' (the plant).
Common Mistakes
- Spelling: 'bushing' (correct) vs. 'bushin' or 'bushing' (incorrect).
- Confusing 'bushing' (stationary liner) with 'bearing' (which may contain rolling elements).
- Using it as a verb in general language ('He was bushing the part') is highly non-standard.

Frequently Asked Questions
Not exactly. A bushing is a type of bearing, specifically a 'plain bearing' or 'sleeve bearing' without rolling elements. Bearings can also refer to ball or roller bearings.
Yes, but it is highly technical. 'To bush' means to fit or provide with a bushing. It is almost never used in everyday language.
It depends on the application. Common materials include bronze (for wear resistance), rubber or polyurethane (for vibration isolation), and plastic (for low friction and cost).
The etymology relates to an older meaning of 'bush' as a metal lining for an axle or a guide, possibly from the Middle Dutch 'busse', meaning 'box' or 'tube', not the plant.
