HF Series Oil Change Timetable

HF series spindle inserts run at up to 18,000+ rpm — at those speeds, the oil film is the only thing between smooth running and catastrophic bearing failure. This guide gives the exact oil change timetable for every HF type.

Vindex Industries is a textile spindle manufacturer in India exporting precision spindle inserts and bolsters to 87 countries.

Oil Change Schedule

First oil change: after 24 hours of running.
Second oil change: after 7 days.
After that: top up the oil level every 30 days.

Vindex Oil Change Timetable

Step	Action	When
1	First oil change (run-in)	After 24 hours of running
2	Second oil change	After 7 days
3	Oil-level check & top-up	Every 30 days

Note: the catalogue table below lists the manufacturer's maximum full oil-change intervals (5,000–10,000 operating hours depending on type and load). The 30-day oil-level check and top-up above is Vindex’s recommended level maintenance between full changes — it prevents dry running and never conflicts with the catalogue schedule.

At every oil change, coat the roller bearing thoroughly with fresh oil before putting the bolster back into service.

HF Series Oil-Change Intervals — Catalogue Reference

Type	Application / Speed	Interval	Grade
HF 1	Up to 18,000 rpm	20,000 h (~28 mo)	VG 10
HF 21	Above 18,000 rpm	12,000 h (~17 mo)	VG 10
HF 33	With ring & traveller	15,000 h (~21 mo)	VG 10
HF 35	Suppressed balloon	10,000 h (~14 mo)	VG 68
HF 44	With ring & traveller	15,000 h (~21 mo)	VG 10

Level Checks

Check oil level on a random sample of spindles after half the interval hours (e.g. 10,000 h for HF 1). Never run below the level mark — dry running causes overheating and twist failure.
