Chapter CXL: Section 70: Anti-Friction Bearings

(_See also p. 152._)

=2402. Roller bearings for centrifugal milk separators, &c.= The pan is carried on three large rollers running against an inverted cone, as shown.

=2403. Ball bearing for vertical shaft.= By Sir Gabriel Stokes.

=2404 & 2405. Forms of grooves for ball bearings,= running horizontally, showing points of bearing in grooves.

=2406. Roller bearing for a vertical shaft,= with steel balls between the ends of the cone rollers to separate them and reduce their friction.

=2407. Roller bearing for a door,= or other article having a limited travel. The roller runs on the floor, or a rail, and its spindle rolls along the slot, the length of which is proportioned to the travel of the door.

=2408. Double cone rollers= for a table having a horizontal circular motion.

=2409. Roller bearing for wagon axle,= with balls between the roller ends to separate them and prevent internal friction.

Anti-friction screws. See Nos. 2413, 2414.

Anti-friction worm gear. See No. 2451.

=2410. Vertical ball bearing,= with bearing surfaces adjusted to receive the direct thrust of the balls.

=2411. Suspended ball bearing.=

=2412. Ball or roller axle bearing.=

=2413. White’s anti-friction ball bearing screw and nut.= A.D. 1822. Square thread screw, the balls travel round the screw thread, and by a pass-groove back to the other end again.

=2414. Lieb’s anti-friction screw and nut,= similar to the last, but with a concave grooved screw. A.D. 1890.
