How the 6013-RSR-NTN model number is decoded
6013-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 13 by five gives the 65 mm bore; the 100 mm outside diameter and 18 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 65 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 6013LLB), mapped here from the industry-neutral -RSR spelling; speed capability matches the open bearing but it is not liquid-tight.
Typical equipment & failure modes
Common applications
- conveyor drives
- material-handling equipment
- industrial fans
- industrial electric motors
Known failure patterns
- ingress of fine dust or moisture past the non-contact lip in dirty or wet duty (RSR is not liquid-tight)
- lip-lubricant starvation if the bearing runs dry for extended periods
- brinelling from static overload or hammering during mounting
- false brinelling from vibration while the shaft is stationary
Selection pitfalls — read before you substitute
- Interference on a 65 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6013 with C3 clearance and re-check the residual value after mounting.
- The 60xx extra-light section at 65 mm bore uses a smaller 100 mm OD than a 6213; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- The low-drag lip of 6013-RSR-NTN barely touches the inner ring; after long shelf storage the grease can separate, so rotate the rings by hand and confirm smooth, silent running before fitting.
- The non-contact lip of 6013-RSR-NTN does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 65 mm bore position before relying on it as sealed-for-life.
- Measure the shaft, do not trust the drawing: a 65 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6013-RSR-NTN.
- Vibration during standstill brinells the raceways of a 65 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- NTN catalogues this low-friction non-contact seal as 6013LLB (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).
- At 65 mm bore 6013 is in NTN's upper general-purpose range; the pressed-steel cage is standard but mid-section 63xx sizes at this bore can be ordered with a machined brass cage (suffix M) for heavy-shock or very-low-speed duty — confirm cage material with the NTN channel if the application sees impact loads.
- At 6500 r/min the grease limiting speed for 6013 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
- At 34 kN dynamic load rating (C) and 25.2 kN static (C0), 1.83 kN fatigue load limit Cu, 6013 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 421 g, 6013 requires a soft-jaw vise or arbor press for mounting — never hammer it onto the shaft, and support the opposite ring to avoid brinelling the raceways.
- The 65×100×18 mm envelope of 6013 gives a D/d ratio of 1.54 and 17.5 mm radial section height — this thin section saves space but is sensitive to misalignment and shock; confirm the housing stays round within IT7 and the shaft does not deflect past the raceway contact angle under load.
- The 34/25.2 kN load ratings, 1.83 kN fatigue load limit Cu NTN lists the grease limiting speed at 6500 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 421 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6013LLB on the 65×100×18 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6013 in a rated drive.
- 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.
- Two NTN bearings of the same designation from different production lots can carry minor internal-geometry revisions; for paired or preloaded arrangements on one shaft, order a single lot through the NTN distributor.
Frequently asked questions
What are the dimensions of a 6013-RSR-NTN bearing?
A 6013-RSR-NTN deep-groove ball bearing has a 65 mm bore, 100 mm outer diameter and 18 mm width (2.559 × 3.937 × 0.709 in), per ISO 15 boundary dimensions. It is fitted with two low-friction non-contact rubber seals.
How should 6013-RSR-NTN be mounted?
Apply the mounting force to the ring being fitted: on a 65 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 6013-RSR-NTN need?
6013-RSR-NTN is supplied pre-greased for life and is not designed to be opened for relubrication; where a relubrication path is required, specify the open 6013 with a housing grease fitting instead.
What is the NTN suffix for a sealed 6013?
NTN uses suffix LLU for the contact rubber seal (catalogue number 6013LLB), LLB/LLF for non-contact rubber seals, LLH for the low-torque contact seal and ZZ for steel shields. The industry-neutral spellings on this page (-2RS / -RSR / -ZZ) map to those NTN suffixes while keeping the 65×100×18 mm ISO 15 envelope.
Does NTN offer 6013 with C3 clearance?
Yes — most NTN deep-groove sizes can be ordered with C3 internal clearance (suffix C3 follows the seal code). C3 suits tight fits and hot shafts; for normal fits at moderate temperature the standard CN clearance of 6013LLB is the correct choice.
