DodgeINS-ER-SC-012Ball Bearing Inserts – 3/4 in Bore, 1.85 in Spherical OD, Setscrew Locking, Extended Inner Ring, 2 Pcs

Product Description

What this part is: Dodge INS-ER-SC-012 ball bearing inserts, Dodge part number 127375. Bearing type: Mounted ball bearing insert, spherical outside diameter. Bore / Shaft Size: 3/4 in (0.75 in). Outside Diameter: 1.85 in. Locking Method: Set screw. Rolling Elements: Balls, chrome steel. Number Of Rows: 1. Duty rating: standard duty. Decoding the designation: INS — insert. The bearing element on its own, with a spherical outside diameter that seats into a matching Dodge housing. ER — the Dodge ER extended-inner-ring ball bearing series. The inner ring runs wide on both sides of the balls, which gives the setscrews a long grip on the shaft and steadies the insert against tipping. SC — setscrew locking. Setscrews in the extended inner ring clamp onto the shaft. 012 — Dodge bore code, read as whole inches and sixteenths: 0-12/16 = 3/4 in shaft. 127375 — Dodge stock number for this build, the number distributors order against. What these specs mean in practice: Bore / Shaft Size: 3/4 in. Outside Diameter: 1.85 in. Dynamic Load Rating: 2,915 lb. Static Load Rating: 1,482 lb. Rolling Elements: chrome steel balls. The spherical outside diameter lets the insert swivel in its housing seat, so angular error between shaft and frame is taken up at installation rather than being carried as a preload on the raceways. The extended inner ring spreads the setscrew grip over a longer length of shaft than a plain-width insert manages, which is what keeps a small-bore unit like this from working loose under vibration. Setscrew locking is the quickest form to fit and to strip, and it holds well where rotation runs consistently in one direction. Housing style and mounting form: The 1.85 in spherical outside diameter mates with Dodge ER-series and SC-series housings in the pillow block, two-bolt flange, four-bolt flange, take-up and hanger ranges at the 012 shaft size. The insert is the wearing part of those units and is replaced independently of the housing. Quantity and configuration: Unit Quantity: 2 Pcs. Two INS-ER-SC-012 inserts ship together in one purchase, each complete with its setscrews. Mounting data: Bore / Shaft Size: 3/4 in. Outside Diameter: 1.85 in. Outer race profile: spherical. Locking Method: Set screw. Interchange guidance: MPN Variants: INS-ER-SC-012, INSERSC012, INS ER SC 012, 127375. Dodge codes shaft size in whole inches plus sixteenths across the INS range, so the 012 here is the same 3/4 in shaft carried by an INS-SC-012, a P2B-SC-012 pillow block and an F2B-SC-012 two-bolt flange. The Dodge ER-12 insert is the same bearing element by its bare series number.
