Lentšu	Le ra gore
Arc of contact θ	Angle yeo belt e kgwathago pulley go yona. E bohlokwa go pulley ye nnyane; ka fase ga 180° e fokotša maatla (factor Kα).
Banded belt	Di-V-belt tše ntši tše di kopantšwego ke band, go go betwa le go thibela go retologa.
Bottoming	Belt e kgwatha fase ga groove: groove ye e jegilego goba sekšene ye e fošagetšego. E baka slip.
Centre distance C	Bokgole magareng ga bogare bja di-shaft tše pedi.
Cogged / notched	Belt ye e nago le dinotšhe ka fase gore e kobege gabonolo go dipulley tše nnyane le go šoma e tonya.
Datum diameter / datum length	Diameter ya pulley ye e šomišwago go bala le botelele bja belt bjo bo swanago, go datum line. Di šomišwa go dipalo ka moka tša dibelt tša ISO.
Datum width	Bophara bja groove (le belt) go datum line: 8.5, 11, 14, 19 mm go Z/SPZ, A/SPA, B/SPB, C/SPC.
Deflection force	Maatla ao a nyakegago go kgoromeletša belt ka lehlakoreng ka 1/64 ya span ya yona; a šomišwa go tiiša le go lekola go tiiša.
Design power Pd	Maatla a motoro × service factor.
Driver / driven	Pulley ya motoro / pulley ya motšhene.
Effective length	Botelele ka ntle ga belt (di-RMA narrow belt, poly-V).
Effective pull Te	Phapano ya go tiiša (lehlakore le le tiilego ntšha le le hlephilego) ye e fetišago maatla: Te = 1000 P / v.
Groove angle β	Angle ya groove ya pulley, go ka ba 32–38° go ya ka sekšene le diameter.
Idler	Pulley ye e dikologago ka bolokologi ye e šomišwago go tloša go hlepha goba go oketša arc of contact.
Kα (arc correction factor)	E fokotša maatla a belt go di-arc tša ka fase ga 180°.
KL (length factor)	E lokiša maatla a belt go ya ka botelele bja yona.
Matched set	Dibelt tše di dirilwego goba tše di kgethilwego ka botelele bjo bo swanago gore di abelane morwalo go drive ya dibelt tše ntši.
Pitch (di-timing belt)	Bokgole magareng ga meno, mohl. 8 mm go HTD 8M.
Raw-edge	Belt ye e nago le mahlakore a a sehilwego a se nago lešela gore e sware kudu.
Rim speed	Lebelo la pulley ka ntle: go na le mellwane go cast iron (≈ 30 m/s).
Service factor	Palo ye e oketšago ka lebaka la go betwa, torque ya go thoma le diiri tša go šoma.
Slip	Go lahlega mo gonnyane ga lebelo ga V-belt (≈ 1–2 %); slip ye kgolo e baka phišo le go jega.
Span length	Botelele bja belt bjo bo lokologilego magareng ga dintlha tša tangent tša dipulley.
Static (installation) tension	Go tiiša ga belt ge e sa šome, mo go bewago ge e tsenywa.
Synchronous belt	Timing belt: e na le meno, ga e thellele.
Take-up	Go lokiša mo go lego gona go tiiša belt ge e dula le go namologa.
Taper-lock bush	Bush ye e kobilego ye e sehilwego ye e tlemago pulley go shaft; go fetoša bush go fetoša bore.
Teeth in mesh	Palo ya meno a timing belt ao a swaranego go pulley ye nnyane; boloka ≥ 6.
Tight side / slack side	Lehlakore le le gogwago ke pulley ya motoro / lehlakore le le boelago.
Turnover	V-belt e retologa go groove ya yona.
VSD / VFD	Variable-speed (frequency) drive ye e laolago lebelo la motoro.
Wedge belt	Narrow V-belt (SPZ–SPC, 3V/5V/8V) ye e nago le maatla a mantši ka belt.
