A bearing seat assembly for a roller assembly includes a bearing seat; a bearing, arranged inside the bearing seat; a first seal, including at least two sealing lips. The first seal is installed on the bearing seat and is arranged on a first axial outer side of the bearing. At least one sealing lip of the at least two sealing lips of the first seal is arranged around the inner or outer circumference of the first seal. The bearing seat assembly according to the present disclosure realizes enhanced sealing, avoids re-lubrication, improves thermal performance, and prolongs service life.

A support structure for a bellows attached to a slide table, and which is capable of expanding and contracting in a movement direction of the slide table, includes support members that support the bellows, shafts disposed substantially in parallel with the movement direction of the slide table, and bushes that support the support member so as to be capable of moving in the movement direction of the slide table with respect to the shafts. Fluid bearings are formed by supplying a fluid between the bushes and the shafts.

A cutting blade mounting mechanism for mounting a cutting blade to a tip portion of a spindle includes: a blade mount mounted to the tip portion of the spindle; and an air supply unit supplying air to the blade mount. The blade mount includes: a columnar boss section inserted into a through-hole provided in an annular base of the cutting blade; a flange section projecting in a radial direction from a side of a base end of the boss section and having a support surface supporting the cutting blade; and an ejector type blade suction section having a first air passage connecting a supply port supplied with air from the air supply unit and a discharge port discharging air, and a second air passage connecting a suction port opening to a side of the support surface of the flange section and the first air passage.

A gib includes a metallic substrate having a first face and a second face and an attachment disposed on the metallic substrate. The attachment includes a first functional surface disposed on the first face of the metallic substrate. The first functional surface is configured as a bearing surface. The attachment may be formed of a fabric resin composite material.

In order for contaminants (50) that are in particular liquid or highly viscous or solid and impact in an operating portion (40b) of one or 2 processing shafts (40.1, 40.2) that rotate adjacent to each other not to reach bearings (2) of the shafts (40.1, 40.2) which are arranged axially outside of the processing portion (40b) which could damage the bearings a wiping device (6) is arranged there between which is additionally axially shielded by a bearing plate (3) and a splash guard plate (4) wherein the wiping device provides that contaminants (50) that reach the wiping section (40a) are wiped off at this location and cannot move further through the bearing plate (3) to the bearing (2) that is arranged outside of the bearing plate (3).

Methods for forming improved bales may include using baling equipment with multi-component bolster assemblies that may ease installation and removal, reduce wear and tear and maintenance, and/or improve efficiency by reducing material waste, imperfections, and/or contamination. The bolster assemblies may include a plurality of coupling portions that engage a hydraulic rod and may enable the bolster assembly to self-center within a press chamber during normal baling operations. The bolster assemblies also may include an island portion that may be attached to the coupling portions and to a bolster cap, and the latter may be attached using retainer bolts having substantially planar heads that may define lips that run about frustums. The bolts may substantially planar head may reduce irregularities in the bale and the lips may prevent material seepage into the bolster assemblies.

A container blank handling apparatus (5) for a container blank trimming system (1) for metallic tubular container blanks comprises first and second air bearing body portions having respective arcuate inner surfaces. The first and second body portions are arranged to be moveable with respect to one another between a closed configuration of the apparatus in which the inner surfaces are substantially contiguous so as to form a substantially continuous bearing surface which defines a container blank receiving volume of the apparatus, and an open configuration of the apparatus in which the first and second body portions spaced apart from one another such that the inner surfaces are not contiguous with one another. One of the first and second body portions defines an air delivery pathway therethrough, the air delivery pathway terminating in at least one air delivery aperture in the inner surface of the body portion such that the air delivery pathway is contiguous with the air delivery aperture, the pathway and aperture being arranged for supply of air therethrough into the container blank receiving volume.

A yoke roller assembly includes an inner ring disposed in an outer ring. The yoke roller assembly includes first, second and third rows of rollers positioned between the inner ring and the outer ring. The outer ring has a first width, a first outside diameter and a radially outwardly extending lobe circumferentially extending therearound and formed integrally therewith. The lobe has opposing axial end faces extending a second width, and has a second outside diameter. The second row of rollers are positioned axially inward of the axial end faces of the lobe. The first and third row of rollers each have an axial end positioned axially inward of the axial end faces of the lobe.

A method for lubricating a radial bearing of a food cutter assembly is disclosed. The method can include receiving a supply of water at a housing for rotationally mounting a spindle body having a rotational axis, where the housing includes a radial bearing proximate to a thrust disc of the spindle body. The thrust disc can include opposing surfaces extending radially from the rotational axis of the spindle body and a circumferential surface between the opposing surfaces. The water can be directed through fluid passages extending from a port in the housing through the radial bearing to the spindle body and across the opposing surfaces and the circumferential surface to the spindle body. The spindle body may be rotated while the water is directed through the fluid passages to create a water film between the housing and the spindle body that reduces friction between the housing and the spindle body.

A food cutter assembly can include a spindle body defining an interior passage for receiving a food product. The food cutter assembly can also include a thrust disc connected to the spindle body. The thrust disc can include opposing surfaces extending radially from the rotational axis of the spindle body and a circumferential surface between the opposing surfaces. A cutting tool can be connected to an end of the spindle body for cutting the food product. The food cutter assembly can also include a housing for rotationally mounting the spindle body, where the housing includes a radial bearing to be positioned proximate to the thrust disc. The spindle body and the housing can define fluid passages extending from a port in the housing through the radial bearing to the spindle body and across the opposing surfaces and the circumferential surface to the spindle body.
