17.040.10 - Limits and fits

This document specifies tolerances on form and position as well as the surface roughness of shafts, flanges and thrust collars as used in plain bearing units. It is applicable to journal or thrust plain bearing units or to a combination of both, installed either horizontally or vertically.
This document is not applicable to crankshaft bearing units in combustion engines.

This document illustrates the ambiguity caused by the use of dimensional specifications to control
properties other than linear or angular size and the benefit of using geometrical specifications instead.
Dimensional tolerancing can be indicated by ± tolerancing or geometrical specifications.
The ambiguity caused by using ± tolerances for dimensions other than linear or angular sizes (for
individual tolerances and general tolerances according to, e.g. ISO 2768-1 and ISO 8062-3) is explained

This document establishes complementary rules to ISO 1101 to be applied to pattern specifications and
defines rules to combine individual specifications, for geometrical specifications e.g. using the symbols
POSITION, SYMMETRY, LINE PROFILE and SURFACE PROFILE, as well as STRAIGHTNESS (in the case
where the toleranced features are nominally coaxial) and FLATNESS (in the case where the toleranced
features are nominally coplanar) as listed in Annex C.
These rules apply when a set of tolerance...view more

ISO 8062-4:2017 specifies general geometrical tolerances using surface profile tolerances related to a general datum system that remains on the final part. It also specifies machining allowances and draft angles (tapers) for castings in all cast metals and their alloys produced by various casting manufacturing processes. NOTE When there is no datum system (target or integral) on surfaces remaining in the final condition, this document cannot be applied.

SIST EN ISO 1101 defines the symbol language for geometrical specification of workpieces and the rules for its interpretation. It provides the foundation for geometrical specification. The illustrations in this document are intended to illustrate how a specification can be fully indicated with visible annotation (including e.g. TEDs).

This document gives the rules for geometrical specifications of integral and derived features, using the
line profile and surface profile characteristic symbols as defined in ISO 1101.

This part of ISO 14405 establishes the default specification operator for angular size and defines a number of special specification operators for features of size with angular size (e.g. wedges or cones).
This part of ISO 14405 also defines the specification modifiers and the drawing indications for these angular sizes.

ISO 1938-2:2017 specifies the most important metrological and design characteristics of reference disk gauges.
ISO 1938-2:2017 covers linear sizes of the gauge up to 500 mm.

ISO 14405-3:2016 establishes the default specification operator for angular size and defines a number of special specification operators for features of angular size: cone (truncated, i.e. frustum, or not), wedge (truncated or not), two opposite straight lines (intersection of a wedge/truncated wedge and a plane perpendicular to the intersection straight line of the two planes of the wedge/truncated wedge, intersection of a cone/frustum and a plane containing the axis of revolution of the cone/f...view more

This part of ISO 14405 establishes the default specification operator (see ISO 17450‑2) for linear size
and defines a number of special specification operators for linear size for features of size, e.g. “cylinder”,
“sphere”, “torus,”1), “circle”, “two parallel opposite planes”, or “two parallel opposite straight lines”.
It also defines the specification modifiers and the drawing indications for these linear sizes.

This European standard specifies tolerances on dimensions and shape for hot-rolled uncoated embossed steel strip and plate/sheet cut of it with a maximum width of 2200 mm and thicknesses up to 20 mm, of non-alloy and alloy steels.

This part of ISO 4759 specifies tolerances for flat washers of product grades A, C and F with nominal
diameters of 1 mm to 150 mm inclusive, designed to be used in bolted joints in combination with bolts,
screws, studs and nuts.
This part of ISO 4759 may be applied to non-flat washers however it does not include all the tolerances
related to these washers.
It applies to non-captive and captive washers, and to standard and non-standard washers.
It does not apply to dynamic disc springs.
