Four alloy-steel pulley bearings for the Jatco JF015E CVT7 in Nissan Versa, Sentra, Note and Micra, 2012 and up.
A Nissan Versa, Sentra, Note or Micra with the small JF015E CVT that whines under light throttle, growls as speed rises, or leaves metallic glitter on the pan magnet may have pulley bearings that are breaking down. This is the bearing set for the pulley shafts: four alloy-steel ball and roller bearings, set number JF1501, that support the primary and secondary pulleys inside the case. Install them whenever the pulleys come out for a belt, a pulley set or a full rebuild.
In the JF015E (Nissan RE0F11A, Jatco CVT7) the engine drives the primary pulley and the steel push belt carries torque to the secondary pulley, which in turn drives the two-speed auxiliary gearbox. Line pressure squeezes the pulley halves to hold the belt, and Gears Magazine reports those pulleys can see as much as 850 psi. Every bit of that clamping load and drive torque ends up in the bearings at each end of the two shafts. They also hold the pulleys in line with each other. Once a bearing gets rough or develops end play, the pulleys tilt slightly, the belt stops riding square on the sheave faces, and wear speeds up. The CVT7 also mounts its pulleys higher in the case, above the fluid in the sump, to cut drag and aeration, so these bearings depend on clean fluid fed under pressure.
Bearing noise on a CVT is easy to confuse with a worn belt, a failing pump or wheel bearings. Road test with a stethoscope or chassis ears and note whether the noise follows road speed or engine speed. Then drop the pan and look at the magnet. Our CVT failure patterns guide explains what each type of debris means. With the unit apart, spin every bearing by hand and check for pitting and rough spots, as Gears Magazine advises. If the sheave faces are scored or the internal balls and rollers are worn, bearings alone will not save the pulleys. See the Jatco CVT problems and fixes guide.
Listed for JF015E / RE0F11A applications from roughly 2010-2015 and up, depending on the vehicle: Nissan Versa, Sentra, Note, Micra, March, Juke, Almera, Livina, NV200 and Tiida; Chevrolet Spark; Mitsubishi Mirage, Attrage and Lancer; Renault Scala; and several Suzuki kei and compact models. Many of these vehicles also came with larger Jatco CVTs such as the JF011E, which share no bearings with this unit. Read the code on the case tag, or compare the old bearing sizes before you order. If you are unsure, send us your year and VIN. All parts for this unit are on our CVT collection page.
For a complete overhaul at the same time, add the JF015E rebuild kit with frictions, steels and filters.

Four alloy-steel ball and roller bearings, set number JF1501, for the primary and secondary pulley shafts of the JF015E / RE0F11A CVT.
Usually not. Rogue and Altima use larger Jatco CVTs, which take different bearings. This set is only for the JF015E / RE0F11A. Check the code on the transmission tag.
It can be either one, or the pump. Bearing noise usually follows road speed and gets worse with heat. Bright metal on the pan magnet means something is wearing internally. You only know for sure once the unit is apart and you can spin each bearing by hand.
Inspect the belt and pulleys, and replace the belt if it is worn. Always replace both filters, and clean the valve body, because bearing debris travels through the hydraulic system. Most people do a full rebuild kit while the unit is apart.
Yes. Any time the transmission comes apart, fill it with NS-3, update the TCM software and run the scan-tool resets, including the clutch point relearn.
