How the 6036 model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6036 carries bore code 36 = 180 mm. Outside diameter 280 mm and width 46 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 180 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- industrial fans and blowers
- hoists and winches
- heavy conveyors
- pulp and paper machinery
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- At 180 mm bore the ring mass is significant: heat 6036 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
- The 60xx extra-light section at 180 mm bore uses a smaller 280 mm OD than a 6236; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- Storage matters for open bearings: 6036 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6036 units.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- Vibration during standstill brinells the raceways of a 180 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- The open 6036 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6036-2Z (shields) and 6036-2RSH (contact seals), not suffix-free 6036.
- The 190/200 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6036 bearing?
A 6036 deep-groove ball bearing has a 180 mm bore, 280 mm outer diameter and 46 mm width (7.087 × 11.024 × 1.811 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What internal clearance does 6036 have?
Unless a clearance suffix says otherwise, 6036 is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6036 and verify the residual clearance after mounting.
How should 6036 be mounted?
Apply the mounting force to the ring being fitted: on a 180 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 6036 need?
The open 6036 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
What is the SKF designation and catalogue data for 6036?
In the SKF Rolling Bearings catalogue this size is listed as 6036 — the open (unsealed) execution, 180×280×46 mm per ISO 15. Quoted values: C 190 kN, C0 200 kN, Pu 5.6 kN, limiting speed 3000 r/min, mass 9100 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6036.
