How the 6007-RSR-NTN model number is decoded

6007-RSR uses two non-contact elastomer lips with very low drag; coarse debris stays out, but the bearing is not liquid-tight. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 07 by five gives the 35 mm bore; the 62 mm outside diameter and 14 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 35 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. NTN's non-contact seal suffix is LLB/LLF (catalogue number 6007LLB), mapped here from the industry-neutral -RSR spelling; speed capability matches the open bearing but it is not liquid-tight.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At a 35 mm bore, a shaft-seat burr or an overtight setscrew can score the thin inner ring of 6007-RSR-NTN; check shaft finish and runout (target Ra ≤ 1.6 µm) before pressing it home.
• Choosing the 60xx extra-light section saves radial space at 35 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6207 before committing to the smaller envelope.
• RSR low-friction seals on 6007-RSR-NTN run faster than contact-seal 6007-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 6007-2RS instead.
• The non-contact lip of 6007-RSR-NTN does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 35 mm bore position before relying on it as sealed-for-life.
• The housing bore for the 62 mm OD should be round within IT7; an oval bore pinches the outer ring of 6007-RSR-NTN and shows up later as two-point loaded raceway wear.
• Never mix components between two 6007-RSR-NTN units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• NTN catalogues this low-friction non-contact seal as 6007LLB (suffix LLB), mapped here from the industry-neutral -RSR spelling. NTN rates its speed capability the same as the open bearing, but it is not liquid-tight — for wet or fine-dust duty step up to the LLU contact seal (industry-neutral -2RS).
• The 35 mm bore puts 6007 in NTN's general-purpose industrial range; the standard pressed-steel cage and CN clearance cover most electric-motor and pump duty, but for continuous high-speed use specify the LLH low-torque seal (not LLU) and confirm the housing allows the listed limiting speed.
• At 8200 r/min the grease limiting speed for 6007 covers most general-purpose industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
• At 17.7 kN dynamic load rating (C) and 10.3 kN static (C0), 0.81 kN fatigue load limit Cu, 6007 is a medium-load bearing suitable for most electric-motor and pump duty; the C0/C0r ratio matters for preloaded or thrust-loaded arrangements, so confirm the static safety factor with the NTN catalogue.
• At 155 g, 6007 is light enough for hand assembly but should be pressed on with a fitting sleeve against the inner ring; do not strike the outer ring or cage with a hammer.
• The 35×62×14 mm envelope of 6007 gives a D/d ratio of 1.77 and 13.5 mm radial section height — a standard medium section that balances load capacity and speed; for this geometry the pressed-steel cage is adequate up to the listed limiting speed, and C3 clearance is the common choice for hot shafts.
• The 17.7/10.3 kN load ratings, 0.81 kN fatigue load limit Cu NTN lists the grease limiting speed at 8200 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 155 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6007LLB on the 35×62×14 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6007 in a rated drive.
• Standard catalogue stock of 6007 is the general-purpose execution; for low-noise motor duty NTN offers low-torque seal and special-grease variants in this size class, which are separate order numbers.
• 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 6007 is listed.
