How the 6200-NSK model number is decoded
In the 6200-series (diameter series 2 of ISO 15) the last two digits encode the bore: 6200 carries bore code 10 = 10 mm. Outside diameter 30 mm and width 9 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 10 mm shaft, typical catalogue practice is a j5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. In the NSK catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes ZZ (steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals).
Typical equipment & failure modes
Common applications
- centrifugal and positive-displacement pumps
- gearboxes and speed reducers
- conveyor drives
- material-handling equipment
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
- Temperature rise and interference fits consume internal clearance on this 10 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 6200 with C3 for those conditions.
- The 62xx light series is the default general-purpose section at 10 mm bore; before upgrading to a 6310 for extra capacity, confirm the housing accepts a 30 mm OD and 9 mm width — it is not a drop-in swap.
- The open 6200-NSK has no lubricant retention: grease escapes and contaminants migrate straight into the 10×30×9 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6200-NSK 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.
- Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6200-series position can soften the mixture and leak — clean out the old fill before switching grease types.
- A 10 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
- The open 6200 has no integral sealing; in the NSK E1103 catalogue the protected variants carry suffixes ZZ (non-contact steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals). NSK does not offer a low-torque contact seal equivalent to NTN's LLH in this catalogue — for high-speed sealed duty specify the VV non-contact seal and an external housing labyrinth.
- At 10 mm bore the 6200 sits in NSK's miniature range; NSK ships these sizes with a pressed-steel cage and P0 tolerance as standard, and NSK's EA (extra-precision) or P5 class is a special-order upgrade for spindle duty — do not assume catalogue P0 figures hold for instrument use without an NSK engineering check.
- NSK rates 6200 at 5.6 kN dynamic (C) and 2.39 kN static (C0); this light-to-medium rating suits fractional-horsepower drives and instruments — for conveying or gearbox duty with shock loads, verify the equivalent dynamic load stays well below C.
- At only 32 g, 6200 is a lightweight NSK bearing that can be handled by hand; still, press it onto the shaft with a sleeve against the inner ring — never through the balls or outer ring.
- The 10×30×9 mm envelope of 6200 gives a D/d ratio of 3.00 and 10.0 mm radial section height — a heavy NSK section built for high-load, lower-speed duty; specifying it in a high-rpm motor generates excess heat and shortens grease life, so prefer a 62/63-series there.
- The 5.6/2.39 kN load ratings, mass 32 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6200 on the 10×30×9 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6200 in a rated drive. NSK does not tabulate reference or limiting speeds in the E1103 Part C dimension tables used for this page — consult NSK's separate speed-rating tables before high-speed service.
- NSK's VV non-contact seal keeps frictional torque close to the open 6200; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
- When replacing a failed unit, inspect the shaft and housing seats before fitting the new 6200 — a new bearing pressed onto a worn or oval seat reproduces the original failure mode in a fraction of its expected life.
Frequently asked questions
What are the dimensions of a 6200-NSK bearing?
A 6200-NSK deep-groove ball bearing has a 10 mm bore, 30 mm outer diameter and 9 mm width (0.394 × 1.181 × 0.354 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
Are 6200 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6200 uses the same ISO 15 envelope (10×30×9 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What internal clearance does 6200-NSK have?
Unless a clearance suffix says otherwise, 6200-NSK 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 6200 and verify the residual clearance after mounting.
What is the NSK order number for an open 6200?
NSK lists the open 6200 under the bare designation 6200; protected versions use suffixes ZZ (steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals) on the same 10 mm bore envelope.
What is the difference between NSK VV and DDU seals?
VV is a non-contact rubber seal: low torque, speed close to the open bearing, dust-tight but not liquid-tight. DDU is a contact rubber seal: far better exclusion of moisture and fine dust, at the cost of a lower speed ceiling and higher running torque. 6200 keeps the same ISO 15 envelope either way.
