How the 6200-NTN model number is decoded

6200 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 10 by five gives the 10 mm bore; the 30 mm outside diameter and 9 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 10 mm shaft under normal load, catalogue practice seats it on a j5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. In the NTN catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal).

Typical equipment & failure modes

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-NTN 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-NTN 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.
• Never mix components between two 6200-NTN units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• 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.
• The open 6200 has no integral sealing; in the NTN 2203 catalogue the protected variants carry suffixes ZZ (non-contact steel shields), LLB/LLF (non-contact rubber seals), LLU (contact rubber seals) and LLH (a low-torque contact seal with higher speed capability than LLU). A JR or JRX suffix (printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
• At 10 mm bore the 6200 sits in NTN's miniature range; ABEC-1/P0 runout is standard, and the pressed-steel cage is adequate up to the grease limiting speed — for higher accuracy (spindles, instruments) ask NTN for a P6 or P5 tolerance-class listing before relying on catalogue P0 figures.
• The 25000 r/min grease limiting speed puts 6200 in NTN's high-speed range; at these speeds relubrication interval shortens sharply and the pressed-steel cage must be checked for cage-bar critical speed.
• NTN rates 6200 at 5.65 kN dynamic (C) and 2.39 kN static (C0), 0.18 kN fatigue load limit Cu; 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 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 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 5.65/2.39 kN load ratings, 0.18 kN fatigue load limit Cu NTN lists the grease limiting speed at 25000 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 32 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E 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.
• NTN's pressed-steel cage (no cage suffix) is the quiet standard for this size; for sustained running close to the limiting speed or for heavy shock duty, ask the NTN channel whether a machined-cage execution of 6200 is listed.
• NTN date-codes its packaging; rotate stock first-in-first-out, because the grease inside sealed units ages on the shelf — after three to five years of storage, check the grease condition before putting the bearing into service.
