Tare da madaidaicin waya na waje na ball bearings: sunan lambar shi ne: UC200 jerin (haske jerin), UC300 jerin (nauyi jerin), da kuma karkataccen kayayyaki UB (SB) 200 jerin, idan amfani da muhalli m, yawanci zaɓi UC200 jerin, akasin haka, zaɓi UC300 jerin. Yawancin lokaci, akwai filayen biyu a kan bearings na waje, kusurwar da ke 120 °, wanda ke da fasali ne lokacin da aka yi aiki tare da shaft, ana amfani da filayen sama a kan shaft, sa'an nan kuma yana taka rawar da ta dace, amma bukatun muhalli shine ƙananan girman oscillation. Wannan waje spherical ball bearings yawanci amfani, da yawa amfani da masana'antu daban-daban na kayan masana'antu, kayan yumbu da sauransu.

Babban amfanin waje spherical yumbu bearings:
