How the 6314-2RS model number is decoded

6314-2RS is closed by two contacting elastomer lips over a lifetime grease fill; the lips add friction, so the speed ceiling sits below the open execution. Within the medium 63xx section (diameter series 3 of ISO 15), multiplying bore code 14 by five gives the 70 mm bore; the 150 mm outside diameter and 35 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 70 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. SKF's contact-seal catalogue number is 6314-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Temperature rise and interference fits consume internal clearance on this 70 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 6314 with C3 for those conditions.
• The 63xx medium section at 70 mm bore gains dynamic rating through larger rolling elements on a 150 mm OD; the penalty is mass and a lower limiting speed than the 6214 — do not specify it for speed-critical shafts.
• Heat is the enemy of the sealed 6314-2RS: sustained running near the lip temperature limit hardens the rubber, after which grease escapes and dirt tracks in — watch the housing temperature in hot drives.
• Never wash a sealed 6314-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
• Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6300-series position can soften the mixture and leak — clean out the old fill before switching grease types.
• The housing bore for the 150 mm OD should be round within IT7; an oval bore pinches the outer ring of 6314-2RS and shows up later as two-point loaded raceway wear.
• SKF catalogues the contact-sealed version as 6314-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 3000 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 9500 r/min thermal reference speed. The single-seal catalogue number is 6314-RS1, used where one shaft side needs external relubrication.
• A one-seal execution 6314-RS1 exists for arrangements that lubricate through the open side; fitting 6314-2RS1 instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
• The 111/68 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.
