The SNR US-G insert bearing is a single-row unit with a spherical outer ring, made to sit in split plummer block housings and bearing units. That spherical seat lets the housing take up small shaft misalignment, which keeps vibration down and makes mounting simpler. You will find it in power transmission, conveying and process equipment where maintenance access matters.
Reading the code helps you order the right piece. The letters US mark an insert with a spherical outer ring. The digits that follow give the shaft size in inches. A hyphenated suffix points to the locking style, and G2 covers how the seal and lubrication are built. So US204-12G2 is a 3/4" shaft with set screw locking, while US204G2 is the same size with another locking method. Quoting the whole number avoids mix-ups at replacement time.
Typical duty covers conveyors, belts, elevators, mixers, blowers and process lines in food, chemical and materials plants, plus agricultural machinery and irrigation equipment. The spherical outer ring is what lets the housing absorb slight misalignment between shaft and support, cutting vibration and helping the assembly last.
When you choose an insert, work from shaft diameter, locking type (set screws, eccentric or taper) and the conditions on site. The G2 sealing holds grease in and keeps dust and moisture out. At mounting, confirm the housing is aligned and tighten the locking screws evenly. Clean the shaft first and keep lubrication on schedule to avoid early failures. On heavily loaded equipment, check the load capacity of the series.
US-G inserts interchange with other makes that follow the same dimensional and locking nomenclature. For a replacement, line up shaft diameter, inner ring width and locking system. If the marking is worn off, the part can still be identified from its dimensions. We can help you find the equivalent that matches both size and mounting type.

Frequently asked questions
- What does the G2 suffix mean on an SNR insert bearing?
- G2 is a design variant of the sealing and lubrication. These inserts use seals that keep dust and moisture out and come greased for service. Send the complete part number by WhatsApp and we will confirm the fit for your application.
- How can I tell if a US204-12G2 insert replaces one from another brand?
- Check shaft diameter, inner ring width and locking system. The US204-12G2 nomenclature is generally compatible across manufacturers, but tolerances and seal type should be verified. If you are unsure, send the dimensions and we will identify the equivalent.
- What lubrication do these insert bearings need?
- SNR US-G series inserts arrive factory-lubricated with long-life grease. Under demanding conditions, inspect the lubricant and relubricate to suit the working environment. For the right grease, contact us on WhatsApp with the bearing part number.
