N 1015 KTN/HC5SP 115 mm 75 mm 20 mm Frequently Asked Questions about N 1015 KTN/HC5SP Super-Precision Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies N 1015 KTN/HC5SP with a precision bore diameter (d) of 75 mm, an outside diameter (D) of 115 mm, and a nominal ring width (B) of 20 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
Model N 1015 KTN/HC5SP is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 75 mm) and steep thermal gradients between inner and outer rings.
The CHG Bearing N 1015 KTN/HC5SP is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for N 1015 KTN/HC5SP. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
